Résumé :
Recent computational models of motor planning have relied heavily on anticipating the consequences of motor acts. Such anticipation is vital for dealing with the redundancy problem of motor control (i.e., the problem of selecting a particular motor solution when more than one is possible to achieve a goal). Computational approaches to motor planning support the Theory of Event Coding (TEC).

Résumé :
When human observers track the movements of their own hand with their gaze, the eyes can start moving before the finger (i.e., anticipatory smooth pursuit). The signals driving anticipation could come from motor commands during finger motor execution or from motor intention and decision processes associated with self-initiated movements. For the present study, we built a mechanical device that could move a visual target either in the same direction as the participant's hand or in the opposite direction. Gaze pursuit of the target showed stronger anticipation if it moved in the same direction as the hand compared with the opposite direction, as evidenced by decreased pursuit latency, increased positional lead of the eye relative to target, increased pursuit gain, decreased saccade rate, and decreased delay at the movement reversal. Some degree of anticipation occurred for incongruent pursuit, indicating that there is a role for higher-level movement prediction in pursuit anticipation. The fact that anticipation was larger when target and finger moved in the same direction provides evidence for a direct coupling between finger and eye motor commands.

Résumé :
Context Biomechanical analyses of cutting tasks have demonstrated kinematic differences associated with the noncontact knee-injury risk when the movement direction is unanticipated. Motor-motor dual tasks occur within dynamic environments and change the demand for attentional resources needed to complete athletic maneuvers, which may contribute to injury risk. Objective To investigate the influence of anticipation and motor-motor task performance on cutting biomechanics. Design Cross-sectional study. Setting Laboratory. Patients or Other Participants A total of 32 healthy, recreationally active men (age = 23.1 ± 3.6 years, height = 180.0 ± 7.0 cm, mass = 81.3 ± 17.3 kg) who self-reported regular participation in cutting sports. Intervention(s) Participants performed a 45° side-step cut on the dominant limb in a random order of conditions: anticipation (anticipated, unanticipated) and task (no ball throw, ball fake, ball throw). Main Outcome Measure(s) Triplanar trunk, hip, and knee angles were assessed throughout the stance phase using 3-dimensional motion capture. Data were analyzed using a time series of means calculated from initial contact to toe-off (0%–100%) with 90% confidence intervals. Mean differences between conditions were identified as regions of nonoverlapping confidence intervals, and those that occurred during the region of peak vertical ground reaction force (0%–25%) are presented. Results Regardless of anticipation, attending to a ball (ball throw) resulted in more trunk extension (range = 2.9°–3.7°) and less lateral trunk flexion toward the cutting direction (range = 5.2°–5.9°). Planning to attend to a ball (ball fake) resulted in less lateral trunk flexion toward the cutting direction (4.7°). During unanticipated cutting, more trunk rotation away from the cutting direction was observed when attending to a ball (range = 5.3°–7.1°). The interaction of anticipation and task had a similar influence on sagittal- and frontal-plane trunk position. Conclusions Motor-motor task performance and its interaction with anticipation induced an upright, neutral trunk position during side-step cutting, which has been associated with the risk for noncontact knee injury. Promoting task complexity during rehabilitation and injury-prevention programs may better prepare individuals to succeed when performing high-risk athletic maneuvers.

Résumé :
Learning how to write involves the automation of grapho-motor skills. One of the factors that determine automaticity is motor anticipation. This is the ability to write a letter while processing information on how to produce following letters. It is essential for writing fast and smoothly. We investigated how motor anticipation processes build up during the period of handwriting automation. Children aged 8, 9 and 10 years had to write two letters ( ll, le, ln) in cursive writing on a digitizer. Motor anticipation referred to processing changes in size ( ll vs. le) and rotation direction ( le vs. ln) of the second letter while writing the l. We recorded three measures on the l upstroke and downstroke. The movement time data indicate that the l upstroke was very variable. The l’s downstroke duration was shorter for ll than le and the latter was in turn shorter than ln. This pattern was already observed at age 8. Trajectory length data revealed that the anticipation of a single parameter such as size change is enough to produce a trajectory increase but the addition of parameters is not cumulative, as we observed for stroke duration. The dysfluency data indicated that at age 8, dysfluency values were equivalent for upstrokes and downstrokes. At ages 9 and 10, the children produced more dysfluency on downstrokes than upstrokes. Previous studies on writing with adults have shown that the anticipation of the following letter affects the production of the l’s downstroke. The production of the upstroke did not vary. This experiment suggests that learning to anticipate in handwriting production requires: a) rendering the movements to produce the upstroke constant; and b) modulating the downstroke as a function of the spatial characteristics of the following letter. The pattern of movement time data suggest that motor anticipation would start to be adult-like at around age 9. Dysfluency and latency measures do not seem to be very informative about the development of motor anticipation in handwriting.

Résumé :
Previous studies on autism have shown a lack of motor anticipation in children and adults with autism. As part of a programme of research into early detection of autism, we focussed on an everyday situation: spoon-feeding. We hypothesize that an anticipation deficit may be found very early on by observing whether the baby opens his or her mouth in anticipation of the spoon’s approach. The study is based on a retrospective analysis from family home movies. Observation of infants later diagnosed with autism or an autism spectrum disorder (ASD) (n = 13) and infants with typical development (n = 14) between 4 and 6 months old show that the autism/ASD group has an early anticipation deficit.

Résumé :
Abstract Introduction. The efficient collection and analysis of information from both the central and the peripheral field of vision may affect human coordination motor abilities. An analysis of the literature on the subject suggests that coordination motor abilities interact with one another, and it is only their combined effect that allows athletes to achieve technical mastery. The main aim of the study was to assess specific coordination motor abilities and to determine how visual perception and reaction time correlate with time-movement anticipation in elite female basketball players. Material and methods. The study participants comprised 17 female basketball players from the Polish National Team aged 18.1 ± 0.8 years. The study involved three ability tests from the Vienna Test System: the Reaction Test (RT, S1), the Peripheral Perception test (PP), and the Time/Movement Anticipation test (ZBA, S2). Results. The analysis of the results obtained proves that the best-developed ability in participants is reaction time, while the other abilities show average development. Study participants were able to develop their response abilities to such high levels by means of practice. A correlation coefficient was found between motor time and tracking deviation (r=0.56), and between time anticipation and the number of correct responses to stimuli appearing in the left (r=0.92) and right (r=0.88) field of vision. Athletes who achieved better results in time anticipation omitted fewer visual stimuli (r=0.7) in the peripheral field of vision. Statistically significant correlations were observed between movement anticipation and reaction time to stimuli in the central field of vision (r=0.58). Conclusions. Perception abilities have a significant effect on time anticipation. The range of one's field of vision does not determine the reaction time to a visual stimulus. Perception efficiency and divided attention, in conjunction with time and movement anticipation, create a complex of specific psychomotor abilities that is indispensable for achieving success in team sports.

Résumé :
Young drivers are overrepresented in motor vehicle crashes, and are shown to be poorer at anticipating potential threats on the roadway compared with their more experienced peers. Literature demonstrates the effectiveness of driver training programs at improving young drivers’ latent hazard anticipation performance. Various hazard anticipation training studies have been undertaken on different population demographics using different training scenario presentation modes and multiple evaluation testbeds. These error-based feedback training programs (3M) allow trainees to make a mistake, show them how to mediate the mistake, and provide an opportunity to master the target skills. The current meta-analytical review focused on 19 peer-reviewed training studies that utilized eye movements to measure improvements in drivers’ latent hazard anticipation performance following training. The role of four moderating factors (mode of delivery – PC-based or non PC-based; presentation of training – egocentric or exocentric; method of evaluation – on-road or driving simulator; and age of sample – teen novices aged 16–17 or young drivers aged 18–21) on the training effects were explored. Overall, the current meta-analysis suggest that: (a) superficial improvements in training programs does not necessarily further improve the drivers’ latent hazard anticipation; (b) drivers who completed a training program with both egocentric and exocentric training views achieved greater levels of latent hazard anticipation performance than those who completed a training program that contained either view, but not both; and (c) the effect sizes of the 3M-based training programs on latent hazard anticipation were greater for drivers aged 18–21 years than drivers aged 16–17.

Résumé :
The purpose of this study was to examine the effect of mood lability on anticipation timing performance. The influence of gender and stimulus speed on timing error was also analysed. Spectral analysis was used to quantify frequency of mood change. The within-subjects standard deviation was calculated as a measure of intensity of mood change. Thirty-eight physical education students (18 men; M = 23.8 yrs, SD = 2.1 and 20 women; M = 20.4 yrs, SD = 1.6) participated in this study. Mood changes were measured along the Pleasantness and Energetic dimensions of the Affect Grid. Performance was assessed using the Bassin Anticipation Timer. It was hypothesized that: the fast mood changers would incur greater timing errors than the slow mood changers, men would perform with less error than women, and stimulus speed would have a significant influence on timing error.
Mixed factorial ANOVAs with repeated measures on the last factor were utilized to compare mean timing error scores: constant error, absolute error, variable error, and total error, over two levels of frequency of mood change (fast/slow) and intensity of mood change (high/low) groups, two levels of gender (men/women) and four levels of stimulus speed (5/10/15/25 mph). Alpha was set at the.05 significance level for all statistical comparisons. Results showed that intensity of mood change had a significant influence on anticipation timing performance, frequency of mood change factor did not have a significant effect on timing error, men performed with less variability than women and stimulus speed had a significant influence on anticipation timing. The Profile of Mood States (POMS) results, showed that women scored lower on the negative mood states than men. Total mood disturbance for both men and women showed no significant relationship to the timing error scores.

Résumé :
This PhD thesis implemented a mixed-methods approach to investigate individual differences in performance, learning, and transfer of expert athletes’ capabilities to anticipate. In study 1, international field hockey goalkeepers and coaches were interviewed to understand their beliefs regarding anticipation of the drag-flick in penalty corners. Participants reported that pre-match video analysis, perception and action, as well as psychological factors are vital to anticipate the drag-flick. Study 2 employed a single-subject design and video-based temporal occlusion paradigm to investigate individual differences in expert and emerging-expert male field hockey goalkeepers’ integrated pick-up of contextual and opponent kinematic information for anticipation. Results indicated some expert and emerging-expert goalkeepers were able to integrate these sources of visual information to anticipate. Thereafter, a sub-sample of goalkeepers participated in a video temporal occlusion anticipation training program with pre, post, retention video tests, as well as a pre-post transfer field test. Some goalkeepers received the intervention and some did not. All intervention goalkeepers, but not the controls, improved on aspects of the video temporal occlusion and field penalty corner tests. Match statistics for two goalkeepers who received the training were also tracked using a multiple-baseline design. Results indicated no improvement in the control baseline phases, but an indication of improvement post-intervention. Study 3 employed a single-subject design to investigate individual differences in expert and emerging-expert female field hockey goalkeepers integrated pick-up of contextual and kinematic information to anticipate across female and male opponents. Results indicated some goalkeepers were able to transfer the capability to anticipate the drag-flick across different opponents. Overall, these findings advanced theoretical knowledge of visual anticipation through an individualized approach in a population of truly expert participants. Furthermore, the findings provide practical implications for skill acquisition specialists, sport psychologists, and coaches to evaluate and improve the visual anticipation of their athletes.

Résumé :
L'empathie nous permet de comprendre et de réagir aux sensations des autres individus. Regarder une situation douloureuse peut induire des comportements de type prosociaux orientés vers les autres ou des réponses d'évitement comme celles enregistrées en réponse à une menace. Le but principal de cette thèse était d'étudier les comportements d'approche/évitement et freezing qui se produisent soit en observant la douleur des autres, soit pendant l'anticipation de la douleur. Deux tâches manipulant la prise de perspective ont permis d'enregistrer des cotations supérieures concernant le niveau de douleur, des temps de réaction inférieurs (expérience 1) et des index de réponses d'évitement plus grands (expérience 2) pour la perspective consistant à imaginer que le sujet représenté dans une condition douloureuse était la personne la plus aimée. Dans la troisième expérience, nous avons analysé le comportement du freezing au niveau du système corticospinal du participant : un effet du freezing spécifique fut rapporté uniquement lorsque de la présentation des stimuli douloureux en perspective du première personne. Dans une quatrième expérience, l'effet du freezing, normalement présent en réponse aux stimuli douloureux fut aussi rapporté dans le cadre de l'anticipation de la douleur pour soi-même. Nos études suggèrent que ce sont principalement les mécanismes cognitifs de prise de perspective qui modulent la réponse empathique et que la perspective de la personne la plus aimée induise la réponse empathique la plus forte. Au contraire les réponses du freezing des modulations corticospinales sont principalement observées lorsque le sujet adopte une perspective en première personne
Empathy allows us to understand and react to other people feelings. Regarding empathy for pain, a witness looking at a painful situation may react to other-oriented and prosocial-altruistic behaviors or self-oriented withdrawal responses. The main aim of this thesis was to study approach/avoidance and freezing behavioral manifestations that co-occurring along with both others’ pain observation and during the anticipation of pain. In two perspective-taking tasks, we investigated the influence of the type of relationship between the witness and the target in pain. Results showed that higher pain ratings, lower reactions times (experiment 1) and greater withdrawal avoidance postural responses (experiment 2) were attributed when participants adopted their most loved person perspective. In experiment 3, we analyzed the freezing behavior in the observer’s corticospinal system while subject was observing painful stimuli in first-and third-person perspectives. Results showed the pain-specific freezing effect only pertained to the first-person perspective condition. An empathy for pain interpretation suggests empathy might represent the anticipation of painful stimulation in oneself. In experiment 4 results, we found that the freezing effect present during a painful electrical stimulation was also present in the anticipation of pain. In conclusion, our studies suggest that cognitive perspective-taking mechanisms mainly modulate the empathic response and the most loved person perspective seems to be prevalent. In addition, more basic pain-specific corticospinal modulations are mainly present in the first-person perspective and it seems to not be referred to the empathy components

Texte intégral
Résumé :
The current body of work aims to apply Processing Efficiency Theory (PET) and Attentional Control Theory (ACT) to novel dynamic settings by examining how anxiety influences perceptual-cognitive and perceptual-motor skills. Sporting domains and fall-risk in older adults are studied. Applying ACT to a tennis anticipation paradigm examines whether state anxiety influences processing efficiency and the use of contextual information during anticipation. Processing efficiency was reduced under anxiety, while overall response accuracy was unchanged. Furthermore, skilled performers were seemingly less able to utilise contextual information when anxious. Studies in Chapters 4 and 5 sought to test the predictions of PET and ACT compared with those of Reinvestment Theory (RT) in the field of fall-risk in older adults. In Chapter 4, trait anxiety, alongside increasing dual-task demands, produced processing and motoric inefficiencies through reduced visual planning and mean gait velocity. Furthermore, greater and more variable gait velocity reductions were found in those with higher trait anxiety. By contrast, greater reinvestment levels were associated with poorer visuospatial recall, higher stepping accuracy, plus larger and less variable gait velocity reductions. Chapter 5 further investigates the motoric inefficiencies observed in anxious older adults’ gait. The influences of trait anxiety, movement specific reinvestment, and falls efficacy on body segmental control during adaptive turning are studied. Trait anxiety and falls efficacy were mainly shown to influence differing facets of turning behaviour, though both were associated with greater coupling of body segments (en-bloc rotations), whereas, limited support was offered for RT. Overall, PET and ACT were supported when applied to these new dynamic domains. However, discrepancies are discussed due to testing theoretical hypotheses in more representative environments.

Texte intégral
Résumé :
Previous investigations comparing direct versus indirectly cued movements have consistently shown that indirectly cued movements take longer to prepare (Neely and Heath, 2010) and involve the recruitment of additional brain areas (Connolly et al., 2000). This increase in processing time has been associated with the additional cognitive transformations required of the task (Neely and Heath, 2010). In the present study we investigated whether differences between direct versus indirectly cued movements are also reflected in the time course of motor preparation. Participants performed a targeting task, moving directly to the location of a visual cue (i.e., directly cued movement) or to a location that differed by 60˚, 90˚, or 120˚ with respect to the visual cue provided (i.e., indirectly cued movements). Participants were instructed to initiate their movements concurrently with an anticipated go-signal. To examine the time course of motor preparation, a startling acoustic stimulus (SAS, 124dB) was randomly presented 150 ms, 500 ms, or 1000 ms prior to the go-signal. Results from the startle trials revealed that the time course of motor preparation was similar regardless of the angle of rotation required and hence whether it was a direct or indirectly cued trial. Specifically, motor preparation was delayed until less than 500 ms prior to movement initiation for both direct and indirectly cued movements. These findings indicate that similar motor preparation strategies are engaged for both types of cued movements, suggesting that the time to prepare a motor response may be similar regardless of whether a cognitive transformation is required.

ENGLISH ABSTRACT: The purpose of this study was to determine the effects of a perceptual-motor training programme on the coincident anticipation timing and batting performance of university club cricket players. The intervention programme focused on developing players‟ visual attention and concentration. Vickers‟ (2007) Three-Step Decision Training Model was used to structure the training sessions. The study followed a repeated measures experimental design with three groups (experimental, placebo, and control) formed by volunteers from a university club cricket team. The independent variable was a four-week training programme. The dependent variables were coincident anticipation timing and performance on a cricket batting test. Subjects were pre- and post-tested with retention tests occurring after a set period of “no training” following the post-tests. Differences between groups were compared using Kruskal-Wallis ANOVA by Ranks Tests. Differences within each group were compared using multiple Mann-Whitney U-Tests. No significant improvements were observed in the experimental group‟s coincident anticipation timing and batting performance. Although neither coincident anticipation timing nor batting performance significantly improved, further research into the use of Vickers‟ (2007) Model to enhance sport performance is recommended.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die uitwerking van ʼn perseptueel-motoriese opleidingsprogram op die samevallende vooruittydsberekening (“coincident anticipation timing”) en kolfprestasie van universiteitsklubkrieketspelers te bepaal. Die klem van die intervensieprogram het op die ontwikkeling van spelers se visuele aandag en konsentrasie geval. Die opleidingsessies is volgens Vickers (2007) se drieledige model vir besluitnemingsopleiding saamgestel. Die studie het ʼn eksperimentele ontwerp van herhaalde metings op drie groepe (eksperimenteel, plasebo en kontrole) van ʼn universiteitsklubkrieketspan toegepas. Die onafhanklike veranderlike was ʼn vier weke lange opleidingsprogram. Die afhanklike veranderlikes was samevallende vooruittydsberekening, en prestasie in ʼn krieketkolftoets. Proefpersone het voor en net ná die opleiding toetse ondergaan, sowel as behoudtoetse drie weke ná die na-opleidingstoetse. Verskille tussen groepe is met behulp van rangtoetse uit Kruskal-Wallis se variansie-analisemodel (ANOVA) bepaal, terwyl verskille binne groepe met veelvuldige Mann-Whitney-U-toetse vergelyk is. Geen beduidende verbetering is in die eksperimentele groep se samevallende vooruittydsberekening of kolfprestasie waargeneem nie. Hoewel nóg samevallende vooruittydsberekening nóg kolfprestasie aansienlik verbeter het, word verdere navorsing oor die gebruik van Vickers (2007) se model vir die verbetering van sportprestasie aanbeveel.

Résumé :
This chapter explores the significance of the dual meaning of the driver inputs to the thalamus in more detail. What happens to these messages when they reach the cortical hierarchies? Currently we know little about how the cortex reacts to the two meanings of the incoming messages. The efference copies that reach the cortex may act both in the control of movements, as do efference copies in other parts of the brain, and may also act to generate a conscious anticipation of an action and its sensory consequences. Or it may do both, depending on the circumstances. Where the thalamic relay fails for any reason while the motor branch remains functional, actions may be assigned, as in schizophrenic patients, to external agents. For any one cortical area, we need to understand not only the messages it receives from the thalamus but also the motor instructions it sends out and how it fits into the cortical hierarchy.

Résumé :
The primary endpoints of DBS adjustments are functional and as such, are related to the symptoms and signs due to the disease and consequent to stimulation. Thus, effective programming requires the programmer to be an astute clinician in the assessing symptoms and signs. This is not always a straight forward or intuitive process. For example, stimulation of the corticospinal tract can reduce tremor but interfere with other motor functions. Assesments often are complicated by the time required for changes to manifest rendering some assessments impractical in the confines of a clinic visit. A systematic approach is based on a knowledge of the disorder being treated and the regional anatomy around the DBS lead that allows anticipation of possible adverse effects. Effective assessments benefit from use of rating scales and adequate documentation.

Résumé :
This chapter presents evidence that at each level of the thalamocortical hierarchy the strength of our conscious perceptions increases. Conscious processes are not all-or-none effects, they are graded. Four factors may be particularly relevant for understanding the neural production of conscious experiences: (1) the actions of the thalamic gate; (2) the neural activity that anticipates an organism’s actions; (3) the activity of the hierarchy of cortical monitors; and particularly (4) the motor actions produced by the outputs of the cortical monitors and acting on the phylogenetically old parts of the brain: these serve to keep actions in accord with anticipations.

Résumé :
Perception is the first form of representational mind to emerge in evolution. Three types of form are discussed: formal representational structure of perceptual states, formation characteristics in computations of perceptual states, and the form of the visual and visuomotor systems. The book distinguishes perception from non-perceptual sensing. The formal representational structure of perceptual states is developed via a systematic semantics for them—an account of what it is for them to be accurate or inaccurate. This semantics is elaborated by explaining how the representational form is embedded in an iconic format. These structures are then situated in what is known about the processing of perceptual representations, with emphasis on formation of perceptual categorizations. Features of processing that provide insight into the scope of the perceptual (paradigmatically visual) system are highlighted. Relations between these processes and associated perceptual-level capacities—conation, attention, memory, anticipation, affect, learning, imagining—are delineated. Roughly, a perceptual-level capacity is one that borrows its form and content from perception and involves processing that is no more complex or sophisticated than processing that occurs in the classical visual hierarchy. Relations between perception and these associated perceptual-level capacities are argued to occur within the perceptual and perceptual-motor systems. An account of what it is to occur within these systems is elaborated. An upshot is refinement of the distinction between perceptual-level capacities, on one hand, and thought and conception, on the other. Intermediate territory between perception-level representation and propositional thought is explored. The book is resolutely a work in philosophy of science. It attempts to understand perception by focusing on its form, function, and underlying capacities, as indicated in the sciences of perception, rather than by relying on introspection or ordinary talk about perception.

Résumé :
The care-defining characteristics of Huntington’s disease (HD) are that it is (1) neuropsychiatric, (2) autosomal dominant, (3) usually adult onset, (4) degenerative over years, and (5) fatal. Comprehensive care of HD requires an awareness of these features of the disease and careful attention to the timing and nature of the diagnosis and to the management of the motor, cognitive, psychiatric/behavioral, and nutritional/bioenergetic disorders. Genetic counseling and testing, social services, and psychological support for affected individuals and their families are all necessary components of a comprehensive approach to care. Comprehensive care ideally includes a team of health professionals who can collectively manage all of these areas and an awareness of the longitudinal course of the disease so that care is provided proactively, anticipating the next problem or disease milestone, rather than reacting to problems as they arise.

Résumé :
Coordination abilities are a set of human properties manifested in the training process and in competitive activity, which determines the success in the management of motor actions of different coordination levels (Lyach, 2002). According to Anochin (1979), an anticipation is a particular form of “overtaking reflection”, in which the image of the result of the action of its actual appearance (occurrence) is formed in the mind of man. Based on this statement, we will try to improve the performance of athletes. Improving the results by choosing the right action according to the feedback received after the first attempt and focusing attention and actions on rational and pragmatic implementation, which we expect to improve results and reduce repetitions in the study of new actions. In our view, a way to achieve this goal would be through work to improve the anticipation capabilities of athletes. The problem of anticipation in sports games is of utmost importance for achieving victory in the completion between offender and defender. Coordination of movements is related to coordination with objects, people, animals, and machines, the behavior and movement of which are often unpredictable (Videv, 2015). In turn, anticipation produces skill-actions (respectively, counteractions) that are confidently carried out within a fraction of a second, called “improvisation”, which is significantly increased by targeted multi-year preparation from childhood (7-8 years). Based on everything so far mentioned, we decided to test the coordination abilities of athletes and, at the same time, see how they would act in subsequent situations similar to the previous one to improve their performance by applying their anticipation skills. Our results point to our assertion that creating an image of your work and bringing anticipation actions into the implementation of performance, in this case, the implementation of various coordination exercises, would improve the performance of athletes.

Résumé :
Abstract In this paper we review a set of studies showing that when people pick up and move an object they continually adjust their grip force in order to stabilize the object in the hand. These grip force adjustments occur simultaneously with or slightly ahead of fluctuations in load forces and torques related to moving the object. They may therefore be seen as anticipatory and we argue that a key line of research in manipulation should be to understand the integration of sensory motor information to build an internal model of the object and the effector system to support such anticipation.

Résumé :
In this paper, the problem of vehicle stability control using model predictive technique is addressed. The vehicle under consideration is an electric vehicle with an electric motor driving each wheel independently. For the purpose of stability control, it is required that the vehicle tracks a desired yaw rate at all times therefore, extending the linear range of the vehicle dynamics. The desired yaw rate is defined based on vehicle speed, steering wheel angle and road surface friction. The vehicle stability control system considered in this paper consists of a high-level controller that compares the current states of the vehicle with its desired states to determine the required forces and moments at the center of mass, and a low-level controller to track those C.G. forces and moments by adjusting the motor torques on each wheel. It will be shown that a non-predictive low-level controller can have a closed form solution. In order to avoid saturation of the tires, the low-level controller has a penalty function that increases exponentially when the tire forces are close to the limits of saturation to reduce tire forces to keep them within the tires force capacity. In this paper, a model predictive controller is designed as the low-level controller to predict the tire forces and the yaw moment at the C.G. to minimize the tracking error of desired C.G. forces and moments. To keep the tire forces within the tires capacity limit, a penalty function is used at each sample time to penalize control actions that result in excessive tire forces. This adds a level of anticipation to the low-level controller to detect in advance when tires are about to saturate and to choose control actions to prevent that from happening. Since tire capacity limit is treated with an analytical penalty function, it is still possible to find a closed form solution for the model predictive low-level controller. The proposed controller is tested with simulations and the results are compared with a similar non-predictive controller.

Résumé :
Abstract Selection of the correct tortuosity model is critical when performing a pre-planning stiff string torque and drag analysis. Various tortuosity models exist in the literature however selection and calibration can be complicated. This paper presents a methodology to aid in selecting an appropriate tortuosity model as well as real case studies. The goal is to apply a suitable tortuosity to a planned trajectory that will mimic the expected tortuosity along the wellbore. Depending on the directional drilling driving system employed, the trajectory can be smooth or very tortuous with significant additional local doglegs. Overall, the effect of standard tortuosity models on a run-in-hole (RIH) analysis using a stiff string torque and drag model will be investigated. Industry standard tortuosity models such as sinusoidal, random, random with dependent azimuth and helical will be investigated to help identify when they are appropriate depending on the directional driving system employed. In today's high-cost and complex 3D wells, simulations using smooth planned trajectories together with conventional soft-string torque and drag models have shown its limits in anticipating bottom hole assembly (BHA), casing or completion strings lock-up events. Hence, new methodology shall be introduced to better predict field observations. This methodology shows that the applicable tortuosity model may change depending on the directional driving system used. The drilled path or a motor, with a slide-rotate pattern, may be significantly different to that of the cyclical path drilled by a rotary steerable system (RSS). The case study shows that the additional tortuosity that was generated by the directional driving system had a significant effect on predicted hookload margin as well as elevated forces and stresses along the liner. The stiff string torque and drag and buckling model can analytically calculate the contact points which may vary significantly, both axially and radially, in a tortuous wellbore. Ultimately the selection and calibration of an applicable tortuosity model is necessary when performing a robust stiff string torque and drag analysis. This ability to correctly apply a tortuosity model in preplanning reduces the risk of BHA, casing and/or completion strings getting stuck or locked-up when running in hole, paving the way for a reduction in non-productive time (NPT) and loss of equipment.
