Flight control system; multiple criteria decision making; multiple objective decision making; multiple attribute decision making; neural network; mean impact value index. Abstract. It is complex and difficult to tune the parameters of the flight controller. To solve such problem, a multiple objective decision making (MODM) method by using the reference model which is built based on the criteria, is proposed. In order to resolve defects of the multiple attribute decision making (MADM) that the arbitrary of the subjective attribute weights and ignoring the objective message of the objective attribute weights, a subjective attribute weights based on the BP neural network by using the MIV (mean impact value) index is proposed. Finally, a combining method based on the TOPSIS is used to give the final attribute weights. The simulation results show that the method could obtain a set of trade-off solutions which satisfy the requirements of the MODM and could tune the controller effectively.

Abstract:
In this article, a design scheme of automatic carrier landing system control law based on combination of the objective risk and the subjective risk is proposed, in order to improve the safety and flying quality of the landing. The nonlinear longitudinal mathematical model is constructed in the air wake turbulence condition during carrier landing, which is transformed into a linear perturbed model by the state-space equations with deviation state variables. The concepts of the objective risk and the subjective risk in the recovery of an aircraft aboard a carrier are addressed. A principle of predicting the future states based on the current ones is put forward so that a mathematic model for the objective risk is established, synthetically considering the current and future landing state deviations. For the other risk, the corresponding model is obtained by the subjective experiences of the pilots in the flight simulation tests. Furthermore, a novel model predictive control algorithm, which contains the additional subjective risk and the time-varying weights of the state terms, is proposed. Automatic carrier landing control law is built by introducing the objective risk, the subjective risk, and the effect of carrier air wake disturbance. In the rolling optimization progress, these time-varying weights are dynamically tuned according to the constantly changing objective risk to control the state deviations and suppress this risk, while the subjective risk is handled by the additional risk terms. Besides, the action of carrier air wake disturbance is considered and compensated in the derivation of the linear matrix inequalities. Test results based on a semi-physical simulation platform indicate that the new automatic carrier landing system control algorithm proposed by this article brings about an excellent carrier landing performance as well as an improved flying quality.

Abstract:
ABSTRACT I empirically investigate the impact of an organization's creativity dependency on the design of its incentive system. In firms for which the primary source of value creation is the creativity of core employees, the designs of incentive systems are particularly challenging. The nature of creative work constrains the feasibility of extrinsic incentives, but at the same time creates a need for them. Accordingly, there is concern that the use of incentives renders people not creative enough, but a lack of incentives makes employees “too creative.” I argue that a solution to this dilemma is the acknowledgment that the decision to use performance-based pay is not made in isolation, but as part of a set of complementary choices. I theoretically argue and empirically show that subjective evaluations of non-task-related performance and performance-based pay are complements in a creativity-dependent setting. I further argue that the intense use of both control mechanisms is the incentive system that best accommodates the control requirements of creativity-dependent firms, and show that the likelihood of choosing this system increases with the creativity dependency.

Abstract:
The object of this paper is to give a g guide for designing the human-robot collaborative control system attaching importance to maneuverability of the operator. The operative ""feel"" is quantitatively evaluated using the norm of input-output signal obtained from the sensors during operation. As an example of the human-robot collaborative system, the subjective operative ""feel"" of the operator is qualitatively analyzed during the sine wave following task using 1-link operation arm. In addition, the control performance of the operator is examined from the viewpoint of H∞ control using the measurement data during the collaborative operation. As a result, it was suggested that the operator executes the given task while adequately reforming the sensitivity function and complementary sensitivity function of the closed loop system of the collaborative system. Use of this method enables design of the control system taking into consideration the operative ""feel"" of maneuverability.

Abstract:
Checklists are a critical component of most any military operation and both the construction of and presentation of checklists can affect the performance and efficiency of these operations. The purpose of this research project is to compare methods for displaying and executing checklists in a command and control operation to increase both performance and efficiency. The NORAD/NORTHCOM Command Center (N2C2) uses a paper checklist system to facilitate responding to any number of disasters, to include air catastrophes. This project investigated the potential effectiveness of a digital system that could take the place of the paper system that is currently being used. A between groups experimental design was used to analyze the relative effectiveness of each method. Each group of subjects was introduced to a timed task on different checklist systems and asked to complete an Air Force Academy Command Center checklist as accurately and as quickly as possible. Performance and subjective assessments of each system were analyzed and compared. The data showed that a linear digital checklist takes a longer amount of time than both a paper checklist and hierarchical digital checklist. In addition, the subjective data showed that the hierarchical system and paper system were easier to use and navigate than the linear system.

Abstract:
In-vehicle voice control systems are standard in most new vehicles. However, despite auditory-vocal interaction allowing drivers to keep their hands on the steering wheel and eyes on the forward roadway, recent findings indicate the potential for these systems to increase levels of workload and lead to lengthy interaction times. Although many studies have examined the distraction potential of interacting with in-vehicle voice control systems, more research is needed to understand the relationship between different system design components and workload. In this study, we investigate the role of system delay, system accuracy, and menu depth in determining the overall level of demand and interaction times on eight different 2017 model-year vehicles. Voice system accuracy was measured via playback of a pre-recorded sample of voice commands through a studio monitor mounted near the headrest. Menu depth and system delay were calculated by measuring, respectively, the number of interaction steps and total system processing time required to access common infotainment functions. These measures were validated through linear and multiple regression analyses with workload and task time collected in an on-road study. We found system delay and system accuracy to be significant predictors of task time and subjective measures of workload from the NASA Task Load Index and the Driving Activity Load Index. A In addition to providing valuable information on the role of separate voice control system design components on resulting levels of workload, these results extend past research by generalizing findings to multiple current auditory-vocal systems.

Abstract:
It is a domestic demand nowadays that people have a pet, plants, and kids or elders at home that must look after on. Sometimes, it is hard to tell if they are living in an appropriate environment where they feel comfortable. That would be troublesome when people go to work or have a vacation, leaving them at home alone. Also, some of the aspects are subjective and difficult to quantify, especially humidity and temperature. In order to reflect the surrounding environment accurately and intuitively, a pet-sitter system is implemented. In this design, the use of high reliability of the Microprogrammed Control Unit (MCU) as the processing core, to improve the pet environment of temperature and humidity, and light to achieve the function of the sub-function design. The main functions of the design include the collection, display, automatic control, and adjustment of temperature and humidity illumination. For the selection of equipment, with the goal of running stability and cost performance, the corresponding equipment is selected, and the final realization of temperature, humidity, and light regulation.

Abstract:
In order to promote the idling noise quality of a single-cylinder gasoline engine, this paper addresses sound source identification and noise control research. The noise was identified by the application of subjective evaluation, acoustic spectrum and sound intensity analysis. It was found that the noise was caused by the anomalous dynamic performance of the timing system under idling conditions. Furthermore, sound and vibration characteristics of timing system were improved by design methodology research of key components. A multi-body dynamic model was established to characterize dynamic characteristics of the timing system under idling conditions. The key factor of producing noise was that the fluctuation of contact force between the chain and guide and transverse displacement of the chain were much higher than those of the allowable design limit. For the lowest design alternation and manufacturing costs, the work analyzed six timing system improvement schemes obtained by cross combination of tensioner blade line and guide strip radian parameters. After that, the optimal design scheme which could improve dynamic performance parameters of the timing system was derived. The design scheme was conducted with a acoustic test of engine to derive the following results. The noise level of a single-cylinder engine under idling conditions decreased by 3 dB(A). The abnormal noise of the original engine was eliminated under subjective evaluation. The sound quality under other working conditions had no apparent deterioration. Research shows that guide and tensioner blade line optimization design could improve dynamic performance of the timing chain system to eliminate abnormal noise, thereby significantly improving the acoustic characteristic of a single-cylinder engine.

Abstract:
AbstractThis paper presents the development of a rotorcraft conceptual design tool able to incorporate handling qualities assessment at an early design stage. After a first conventional sizing, performed utilizing NASA’s NDARC software, a linearized model of the rotorcraft flight mechanics is built. The linear model is augmented by a simplified control system, designed according to structured $$H_{\infty }$$ H ∞ techniques, to determine augmentation requirements, rather than design the actual flight control system. ADS-33 Bandwidth and Phase-Delay standards are exploited to objectively assess the handling qualities of the current design and to drive an iterative redesign process aimed at enhancing the handling qualities ratings. The rotorcraft parameters resulting from the augmented sizing are subsequently used to automatically generate a real-time capable multibody model, which can be used for the subjective evaluation of its handling qualities via piloted flight simulation. The tool capabilities are demonstrated by designing a conventional lightweight helicopter of the class of the Airbus Helicopters BO105.

This thesis covers design, simulation and implementation of a solar energy control system for an on grid energy storage device. The design covers several control methods such as energy balance control, operating mode switching and data exchange. A genetic algorithm was designed to optimize the control system parameters design, and the algorithm's simulation and real time operating system implementation showed comparable results. The control system was implemented to connect a power supply to the grid. The power supply simulated a solar panel and connected to an electrical grid via Energy Hub equipment, and the energy transfer characteristics of designed control system were tested. The results showed that the selected algorithm matches the target performance criteria.

Full text
Abstract:
This thesis presents several fault/failure-tolerant switching control system structures and proposes design methodologies for systems vulnerable to actuator and sensor faults/failures. The working effectiveness of each actuator/sensor (which is assumed to be known by a fault detection scheme) is represented as a time varying parameter \delta(t). Distinct values/factors are set to \delta(t) in order to model components with different functional status and the number is s. If the total number of components is m, then at any time t, there are s^m fault scenarios. The resulting controller is reconfigurable but with a special structure that the system matrices are fixed while the switching is on the parameter \delta(t). Recognizing that it is unlikely that all components will have serious faults at the same time, the design objective is to maintain an acceptable performance level only for a group of faulty systems imposed by a tolerance measure. At the same time, the no-fault nominal performance is optimized. Several relaxation procedures for the fault/failure-tolerant control are proposed to overcome the combinatorial nature of the problem. Sufficient conditions are derived to guarantee that a matrix inequality, which is a quadratic function of a linear fractional function of a structured matrix \Delta, is satisfied for all \Delta satisfying a set of quadratic matrix equalities and inequalities. This new robustness result extends the S-procedure to a wider setting by tackling structured uncertainties that satisfy constraints other than a norm bound and problems that require quadratic rather than linear inequalities. The extension is given in terms of general matrix products and defines dual variables that are required to satisfy definiteness properties for these products. Weaker commutation and definiteness assumptions for standard and block Hadamard matrix products are derived. We also introduce a new generalized block matrix product and extend the Schur product theorem for this product. The weaker constraints on the dual variables, together with the above fault/failure tolerance measure give significantly less conservative designs than current approaches.

Abstract:
Modern industrial society, increasing energy demands, and environmental issues have increased the need for new and clean renewable energy resources, among which photovoltaic energy has gained considerable interest. For best energy utilization, photovoltaic maximum power tracking and grid-integration aspects should be addressed. Generally, variable-step, incremental conductance maximum power point tracking technique has the merits of good tracking accuracy and fast convergence speed. Yet, the division processes in its algorithm create a computational burden. Also the conventional variable step-size encounters steady-state power oscillation and dynamic problems, especially under sudden irradiance changes. In this thesis, a division-free incremental conductance algorithm is proposed for photovoltaic maximum power tracking. It features a modified variable step-size and a direct converter control scheme. The proposed tracking technique does not only have the merits of superior steady-sta te and transient performance but also offers simple implementation and control. Thus, it can be practically implemented using low-cost microcontrollers, reducing overall system cost. Grid integration of photovoltaic systems using power electronic converters that vary in configurations, control loops and mandatory measured signals are investigated. A singlephase two-stage grid-interfaced photovoltaic system is presented in this thesis. It uses a boost chopper in the first stage for maximum power tracking and an H-bridge voltage source inverter in the second stage for grid interfacing. A novel DC-link voltage sensorless control technique is proposed for this topology. It eliminates the inverter outer DC-link voltage control loop, thus reducing system size, cost and control complexity. Additionally, system dynamics are enhanced during sudden changes. Single-stage based grid-tied photovoltaic power converters receive attention due to their merits of reduced footprint and losses, but at the cost of a limited degree-of-freedom. In this thesis, a single-phase single-stage grid-tied photovoltaic system is proposed. It adopts a single transformerless current source inverter to achieve photovoltaic maximum power tacking, whilst satisfying grid interfacing requirements. A proportional-resonant controller, associated with harmonic compensator units, is proposed for the inverter in order to limit injected grid current harmonics. Thus, a lower-sized inductor can be used in the inverter DC-link which enhances efficiency without sacrificing system performance. Simulation and experimental results validate all the proposed systems.

Abstract:
To support concurrent design a framework for hierarchical design of a process operating system is developed. A process operating system is defined as the complete collection of control schemes, alarms and operating procedures used for managing the process through all phases of operation. The design of an integrated operating system is approached by decomposing the problem into a hierarchy of operating tasks. Three classes of operating task are identified: regulatory tasks for optimising operation at a steady state, transition tasks for transferring the process from one regulatory state to another and executive tasks which manage the response to discrete events such as alarms and failures. Operating tasks define the requirements for optimisation and failure management. The implementation of an operating task is achieved by the design of a control scheme for which a generic structure has been developed. The structure emphasises the use of explicit models with parameter estimation and control distribution blocks providing the interface between the abstract model used for optimisation and the reality of the underlying system. A knowledge based representation has been developed to support operating system design. Particular attention has been given to the problem of supporting concurrent design of the process and operating system. A representation has been developed that links process design alternatives with operating system design alternatives by their association with a common operating task. A case study that considers the design of a hierarchical operating system for a hydrofluoric acid plant is included in this thesis. The study demonstrates how the operating system may be developed in step with the process design. The hierarchical development of the process is used to help formulate the operating tasks for the operating system design. Through design of the operating system it is possible to provide focused feedback on the process operability requirements. The final operating system structure demonstrates how failure management and optimisation are integrated together.

Successful multivariable control system design demands knowledge, skill and creativity of the designer. The goal of the research described in this dissertation was to investigate, implement, and evaluate methods by which artificial intelligence techniques, in a broad sense, may be used in a design system to assist the user. An intelligent, interactive, control system design tool has been developed to fulfil this aim. The design tool comprises two main components; an expert system on the upper level, and a powerful CACSD package on the lower level. The expert system has been constructed to assist and guide the designer in using the facilities provided by the underlying CACSD package. Unlike other expert systems, the user is also aided in formulating and refining a comprehensive and achievable design specification, and in dealing with conflicts which may arise within this specification. The assistance is aimed at both novice and experienced designers. The CACSD package includes a synthesis program which attempts to find a controller that satisfies the design specification. The synthesis program is based upon a recent factorization theory approach, where the linear multivariable control system design problem is translated into, and techniques efficiency solved as, a quadratic programming problem, which significantly improve the time and space of this method have been developed, making it practical to solve substantial multivariable design problems using only a microcomputer. The design system has been used by students at the University of Cape Town. Designs produced using the expert system tool are compared against those produced using classical design methods.

Abstract:
Driven by the emergence of autonomous/semi-autonomous driving technologies, the mixed situation of autonomous vehicles and human drivers is of considerable significance. Toward this end, it is necessary to better understand human driving characteristics so as to predict the actions of the other cars. In this regard, we develop a basic framework for modeling driver behaviors in view of human prediction ability. Through the game theoretic estimation of the counterpart’s behaviors and the corresponding time-evolution of unsafe collision areas, we compute an objective collision model. In turn, we design a human-like predictive perception model on collision with an adjacent vehicle based on the objective collision model and the driver’s subjective level of safety assurance. Since drivers have different safety requirements, the subjective estimate on the collision was designed as a region in which has less safety than the driver’s own safety requirement in the objective probabilistic collision prediction. The region that is subjectively perceived based on the driver’s own safety standard is regarded as a deterministic unsafe region for the driver. That is to say, the subjective perception acts as a collision area with the collision probability of 1 so that the driver should avoid while driving. In our subsequent work, we will address the issue of controller design to avoid the subjective collision estimation.

Abstract:
The paper considers the problem of the influence of subjective factors on the effectiveness of the use of visualization tools in the tasks of interpretation and practical analysis of unformalized data. Subjectivity is the starting point in the cognitive search, analysis of new information and proposing new hypotheses. In the methods of studying unformalized data, including the use of modern intelligent methods, the emergence of the stage of interactive communication between the researcher and the data, allowing to combine the data and their possible subjective interpretation in one information space, can give new tools for scientific research and methods of their application Based on the developed semiotic model of visualization, the system of initiating factors that have a significant impact on the performance of the tools is proposed It is shown that visualization tools, their perceived characteristics and control subsystems can form the necessary emotional factors in the user to control his activity. A controllability hypothesis has been formulated to explain the limitations of some visualization systems and to avoid errors in the design of new visual analytics tools. Thus, the design of visualization tools is considered as a complex parameter for managing their purpose and effectiveness. Examples are given to illustrate the validity of the assumptions made and their practical relevance.

Abstract:
In this paper, a comprehensive evaluation method for vehicle handling based on the driver’s subjective evaluation to different vehicle configurations has been studied by using development driving simulator tests. An objective evaluation index is developed which consists of several individual evaluation indices affecting vehicle handling. A series of weighting factors corresponding to individual evaluation indexes are found by using the Genetic Algorithm to reach the best agreement between the objective evaluation and the average of subjective evaluation of the drivers. Simulator test scheme has been designed and carried out with 14 vehicle configurations, and subjective evaluation has been made for easy handling of vehicle by a group of drivers. A driver/vehicle close-loop system model has been established which can predict the vehicle motion of handling and stability. Vehicle design parameters and control parameters of its control system have been optimized by using the driver/vehicle close-loop system model and objective evaluation index.

Abstract:
This paper investigates the possibility of using objective indicators to predict the subjective evaluation of a driver in a simulator. Situations of loss of adherence (LOA) were controlled and modulated in intensity and duration on a static and on a dynamic simulator (with and without a motion base). Multiple regression analyses were performed using the subjective evaluation of participants as the dependent variable, and the objective physical variables of the interaction driver/vehicle as the independent variables. The results assigned the most contributive variables to the accuracy of the model’s prediction for each subjective item, lateral acceleration and yaw rate for “control feeling” for instance. They also underlined the consistency of our approach and the influence of motion rendering on the perception of LOA intensity. A similar method could be used to evaluate the perception of various configurations of electronic stability control (ESC) systems.

Abstract:
Abstract Active aerodynamics is a growing field in the race car and high-performance vehicles segments, since each situation on the track may require different aero forces to achieve the best vehicle dynamics performance. This paper presents an active aerodynamics control system developed through the active control of the body trim. By interchanging four different setups on the suspension heights with a fuzzy logic control, relevant advantage is obtained in terms of lap time reduction. Two systems, a PID and a Feedforward logic, are studied to implement the control strategy and important differences are found in the stability of tire-ground forces benefiting the latter. Furthermore, the system was validated in a Driver-In-the-Loop (DIL) static simulator with a more realistic road conditions and important insights in terms of subjective evaluation.

Abstract:
The main goal of brake by wire technology is the development of compact, cheap and flexible braking systems. Since neither brake fluid nor hydraulic lines are used, brake by wire electro-mechanical actuation is a favourable solution both for production process and environmental aspect, and offer a precise control of braking torque amplitude. One of the most critical aspect is the lack of traditional link between brake pedal and brakes (calliper); this mean a potential safety problem to be correctly managed through the system architecture, redundancies, diagnosis and recoveries. During CRF brake by wire system development several architectures were deeply analysed using PHA, FMEA, and FTA methodology to identify the best configuration for production intent. The selected one is a fault-tolerant architecture based on a time-triggered communication network connecting fail-silent nodes. From safety analysis were defined critical events and system diagnosis and recovery requirements specifications. This paper describes the steps followed in the brake by wire software development, and its validation with respect to safety needs. For this purpose a three levels design and validation process was exploited. First of all, it was defined the complete simulation template including calliper electro-mechanical actuators and theirs ECU, time-triggered communication network and vehicle control ECU. The brake by wire system was interfaced to a complete vehicle dynamics model specifically developed for control design and validation purpose. Within this environment the control software was developed and the strategies were verified applying Software In the Loop technique. Then the ECU software was automatically generated using a customised tool chain based on Real Time Workshop Embedded Coder. Than, Hardware In the Loop testing was adopted to deeply verified high level software (application), low level software (OS, API, drivers,...) and hardware. HIL bench include the complete brake by wire system and a real time platform running the same vehicle model used during previous phase. Finally, vehicle testing phases complete the evaluation in the real environment and allows the system control development and tuning toward performances and subjective aspects. In each phase the system is tested both in normal and faulty conditions; a fault injection campaign was carried on to verify system response to fault with respect to the expected one. The process is cyclical, and a new loop has to be activated for each changes in the system. At the same time, testing complexity increases in order to guarantee the system safety.

Abstract:
Abstract A fuzzy expert system was developed for autonomous in-space identification of spacecraft modal parameters. The in-space identification can be used to validate analytical predictions, detect structural damage, or tune automatic control systems as required. A fuzzy expert system determines accuracy of vibration data analysis performed autonomously using the Eigensystem Realization Algorithm. Evaluation of the data analysis output is imprecise and somewhat subjective. The expert system was developed using the knowledge provided the co-developer of the Eigensystem Realization Algorithm. The accuracy indicator represents the analyst’s degree of confidence in the analysis results. The fuzzy membership functions of the expert system were parameterized and tuned using numerical optimization.

Intelligent technology changes the world, promotes the integration and development of industries, and changes people's way of life and form. The smart home central control system, which is closely related to our daily life, is comfortable, safe, highly stable, and reliable. This research purpose was to explore the affordance of gender visual perception for the interface design of a smart central control system. The experimental was adopted a 2 x 3 mixed factorial design to help explore whether different gender and operation modes may affect users’ visual perception. We employed convenience sampling and recruited a total of 12 participants to participate in this experiment. The experimental data were collected in relation to task performance using the system usability scale (SUS), subjective evaluations, and semi-structured interviews. The generated results revealed that: (1) The task performance shows that the interface design of the smart home central control system affects the participants' visual perception. (2) Females generally believe that the three smart home central control system interface designs are logical and innovative. (3) There was an interaction between gender and operation mode, the logic and innovation of the operation interface affected participants' perception of interaction.

Abstract:
Abstract This paper refers to mathematical tuning, by the sinusoidal steady-state transfer function method, of an adjustable hydraulic rear engine mount for reduction of perceived vibration during engine idle situations. The problem being addressed, in particular, is the reduction of “idle shake”. The accuracy of this method is confirmed by individual component testing along with in situ vibration measurements. During this work, a general approach to transfer function calculation is given by evaluating the system components with the linear-graph system of modeling. This is complemented by component verification and curve-fitting to arrive at the final transfer function which reveals the inherent tendencies of the overall system. Secondary measurements are then employed to rectify the contradiction between mathematical values and subjective results.

Full text
Abstract:
There is an existing issue in human-machine interaction, such that drivers of semi-autonomous vehicles are still required to take over control of the vehicle during system limitations. A possible solution may lie in tactile displays, which can present status, direction, and position information while avoiding sensory (e.g., visual and auditory) channels overload to reliably help drivers make timely decisions and execute actions to successfully take over. However, limited work has investigated the effects of meaningful tactile signals on takeover performance. This study synthesizes literature investigating the effects of tactile displays on takeover performance in automated vehicles and conducts a human-subject study to design and test the effects of six meaningful tactile signal types and two pattern durations on drivers’ perception and performance during automated driving. The research team performed a literature review of 18 articles that conducted human-subjects experiments on takeover performance utilizing tactile displays as takeover requests. Takeover performance in these studies were highlighted, such as response times, workload, and accuracy. The team then conducted a human-subject experiment, which included 16 participants that used a driving simulator to present 30 meaningful vibrotactile signals, randomly across four driving sessions measuring for reaction times (RTs), interpretation accuracy, and subjective ratings. Results from the literature suggest that tactile displays can present meaningful vibrotactile patterns via various in-vehicle locations to help improve drivers’ performance during the takeover and can be used to assist in the design of human-machine interfaces (HMI) for automated vehicles. The experiment yielded results illustrating higher urgency patterns were associated with shorter RTs and higher intuitive ratings. Also, pedestrian status and headway reduction signals presented shorter RTs and increased confidence ratings compared to other tactile signal types. Finally, the signal types that yielded the highest accuracy were the surrounding vehicle and navigation signal types. Implications of these findings may lie in informing the design of next-generation in-vehicle HMIs and future human factors studies on human-automation interactions.
