Texto completoDesigning hybrid powertrains is a complex task, which calls for experts from various fields. In addition to this, finding the optimal solution requires a system overview. This can be, depending on the granularity of the models at the component level, highly time-consuming. This is even more true when the system’s performance is determined by its control, as it is the case of the hybrid powertrain. In fact, various possibilities can be selected to deliver the required torque to the wheels during the driving cycle. Hence, the main obstacle is to achieve optimality while keeping the methodology fast and robust. In this work, novel approaches to exploit the full potential of hybridization are proposed and compared. The first strategy is a bi-level approach consisting of two nested optimization blocks: an external design optimization process that calculates the best fuel consumption value at each iteration, found through control optimization using an improved version of dynamic programming. Two different systemic design strategies based on the iterative scheme are proposed as well. The first approach is based on model reduction while the second approach relies on precise cycle reduction techniques. The latter enables the use of high precision models without penalizing the calculation time. A co-optimization approach is implemented afterwards which adjusts both the design variables and parameters of a new efficient rule-based strategy. This allows for faster optimization as opposed to an all-at-once approach. Finally, a meta-model based technique is explored

Texto completoHybridfordon är ett aktuellt ämne, på grund av den strikta regleringen gällande fordonsutsläpp. Den optimala designen av hybridfordon är nödvändig för att reducera kostnaden eller utsläppen. Motorsystemet hos ett elektriskt hybridfordon blir mer komplicerat än det hos ett konventionellt fordon, eftersom man måste ta hänsyn till försörjningen av elektrisk energi. Designprocessen involverar design av topologi, design av komponenter samt design av kontrollsystem. Idéen om att sammanfoga alla tre designfaser kallas systemnivådesign. På grund av komplexiteten är det tidsmässigt inte möjligt att evaluera samtliga möjliga designval. Därför behövs optimeringsalgoritmer för att snabba på processen. Olika typer av variabler berörs i de olika designfaserna och därför behövs olika algoritmer. I avhandlingen undersöks olika algoritmers robusthet för kontinuerliga och diskreta variabler samt deras prestanda mot en intern optimeringsplattform. Standardiserade testfall används för att validera algoritmerna vartefter algoritmerna görs mer effektiva och generella. Baserat på teoretiska och experimentella studier föreslås rekommendationer för val av algoritmer baserat på olika typer av variabler. Baserat på optimeringsplattformen introduceras flera olika optimeringskoordinationsarkitekturer för systemnivådesign, och samtidiga och samordnade koordinationsarkitekturer testas för ett specifikt industrifall i den andra delen av avhandlingen. Båda metoderna tycktes vara lovande enligt resultatet av testfallet, och de lyckades sänka konvergensperioden dramatiskt. Den använda fordonsmodellen var inte tillräckligt exakt för att bevisa vilken metod som är den överlägsna, men en mer exakt modell kan introduceras i framtiden för att underlätta en sådan slutsats.

Electric aircraft propulsion (EAP) technologies have been a trend in the aviation industry for their potential to reduce environmental emissions, increase fuel efficiency and reduce noise for commercial airplanes. Achieving these benefits would be a vital step towards environmental sustainability. However, the development of all-electric aircraft is still limited by the current battery technologies and maintenance systems. The single-aisle turboelectric aircraft with aft boundary-layer (STARC-ABL) propulsion concept is therefore developed by NASA aiming to bridge the gap between the current jet fuel-powered aircraft and future all-electric vehicles. The plane uses electric motors powered by onboard gas turbines and transfers the generated power to other locations of the airplane like the tail fan motor to provide distributed propulsion. Power electronics-based converter converts electricity in one form of electricity to another form, for example, from ac voltage to dc voltage. This conversion of power is very important in the whole society, from small onboard chips to Mega Watts level electrical power system. In the aircraft electrical power system context, power electronics converter plays an important role in the power transfer process especially with the recent trend of using high voltage dc (HVDC) distribution instead of conventional ac distribution for the advantage of increased efficiency and better voltage regulation. The power generated by the electric motors is in ac form. Power electronics converter is used to convert the ac power into dc power and transfer it to the dc bus. Because the power to drive the electric motor to provide distributed propulsion is also in ac form, the dc power needs to be converted back into ac power still through a power electronics converter. With a high penetration of power electronics into the onboard electrical power system and the increase of electrical power level, potential stability issues resulted from the interactions of each subsystem need to be paid attention to. There are mainly two stability-related studies conducted in this work. One is the potential cross-domain dynamic interaction between the mechanical system and the electrical system. The other is a design-oriented study to provide sufficient stability margin in the design process to ensure the electrical system’s stable operation during the whole flying profile. The methodology used in this thesis is the impedance-based stability analysis. The main analyzing process is to find an interface of interest first, then grouped each subsystem into a source subsystem and load subsystem, then extract the source impedance and load impedance respectively, and eventually using the Nyquist Criterion (or in bode plot form) to assess the stability with the impedance modeling results. The two stability-related issues mentioned above are then studied by performing impedance analysis of the system. For the electromechanical dynamics interaction study, this thesis mainly studies the rotor dynamics’ impact on the output impedance of the turbine-generator-rectifier system to assess the mechanical dynamics’ impact on the stability condition of the electrical system. It is found that the rotor dynamics of the turbine is masked by the rectifier; therefore, it does not cause stability problem to the pre-tuned system. For the design-oriented study, this thesis mainly explores and provides the impedance shaping guidelines of each subsystem to ensure the whole system's stable operation. It is found that the stability boundary case is at rated power level, the generator voltage loop bandwidth is expected to be higher than 300Hz, 60˚ to achieve a 6dB, 45˚ stability margin, and load impedance mainly depends on the motor-converter impedance.

Texto completoMålet med den här studien är att föreslå en el-hybridiserad version av ett framdrivningssystem för ett passagerarflygplan om 10 personer, och jämföra det med ett konventionellt (referens) flygplan som använder fossildrivna turbofläktmotorer för framdrift. Det el-hybridiserade framdrivningssystemet består utav en fossildriven gasturbin vars syfte är att generera elektricitet, kopplat i en seriell konfiguration med ett batterilager, som förser två elektriskt drivna kanaliserade fläktar. Jämförelsen syftar framförallt till energiförbrukning och koldioxidutsläpp; därav, målet är att reducera dessa i el-hybrid lösningen. Flygplanen jämförs när de presterar samma förutbestämda rutt som är 900 km lång, har en kryssning altitud på 7500 m i 150 m/s. Andra rutt parametrar är optimerade, med hänsyn till energiförbrukning. Det el-hybridiserade framdrivningssystemet är utvärderat i tre olika scenarier, som är: 2020- , Near Future- och Anvanced Future scenario, som alla innebär olika komponentegenskaper som representerar olika framtida förutsägelser. Ett experiment är utfört med en småskalig elektrisk kanaliserad fläkt, som körs i en vindtunnel, för att mäta kvantiteter som effekt och framdrivningskraft. Dessa resultat är sedan skalade upp och använda som designparametrar för en föreslagen fläkt design som är tillräckligt stor för att driva det el-hybridiserade flygplanet. Resultaten visar att det el-hybridiserade konceptet, under designförhållandena, visar sig vara möjlig i alla scenarier. Vikten av flygplanet ökar när det el-hybridiserade konceptet är applicerat, men bränsleförbrukningen minskar ändå, där mängden reducerat bränsle i allra högsta grad beror på energi-densiteten i batterierna.

Texto completoReducing CO2 emissions is a major challenge for Europe in the years to come. Nowadays, transport is the source of 24% of global CO2 emissions. Aviation accounts for only 2% of global CO2 emissions. However, air traffic is booming and concerns are emerging. For instance, CO2 emissions from air traffic have increased by 61% in Sweden since the 1990s. This explains the emergence of the "Flygskam" movement which is spreading in more and more European countries. It is in this context that the European Union launched in September 2016 the project Hybrid Aircraft Academic research on Thermal and Electrical Components and Systems (HASTECS). The consortium brings together different laboratories and Airbus. This project is part of the program "Clean Sky 2" which aims to develop a greener aviation. The ambitious goal is to reduce CO2 emissions and the noise produced by aircraft by 20% by 2025. To do that, the consortium is studying a serial hybrid architecture. Propulsion is provided by electric motors. Two targets are defined. In 2025, the engines must reach a power density of 5kW/kg, including the cooling system. In 2035, the power density of the engines will be doubled to reach 10kW/kg. To reach these targets, the voltage level will be considerably increased, beyond one kilovolt. The risk of electric discharges in the stators of electric motors is considerably increased. The objective of this thesis is to develop a tool to assist in the design of the primary Electrical Insulation System (EIS) of the stator of an electric motor controlled by a converter. It is organized in 5 parts. The first part begins by clarifying the issues and challenges of a greener aviation. The electric motor stator EIS is developed. Finally, the constraints that apply to the EIS in the aeronautical environment are identified. The second part presents the different types of electric discharges that can be found. The main risk comes from Partial Discharges (PD) which gradually deteriorate the EIS. The main mechanism for explaining the appearance of PD is the electronic avalanche. The Paschen criterion makes it possible to evaluate the Partial Discharge Inception Voltage (PDIV). Different techniques are used to detect and measure the activity of PD. Numerical models are used to evaluate the PDIV. The third part presents an original method for determining the electric field lines in an electrostatic problem. It only uses a scalar potential formulation. The fourth part presents an experimental study to establish a correction of the Paschen criterion. An electric motor winding is very far from the hypotheses in which this criterion was originally defined. Finally, the fifth part is devoted to the development of the SIE design aid tool. Graphs are generated to provide recommendations on the sizing of the various insulators in a stator slot. A reduction in the PDIV due to a combined variation in temperature and pressure is taken into account

Texto completoThis thesis presents the research of energy management in a battery/ultracapacitor hybrid energy storage system with exogenous disturbance in hybrid electric vehicular application. Transient and harmonic persistent disturbances are the two kinds of disturbances considered in this thesis. The former is due to the transient load power demand during acceleration and deceleration, and the latter is introduced from the process of the internal combustion engine torque ripples compensation. Our control objective is to absorb the disturbances causing battery wear via the ultracapacitor, and meanwhile, to maintain a constant DC voltage and to compensate the self-discharge in the ultracapacitor to maintain it operating at the nominal state of charge. The object system is nonlinear due to the multiplicative relation between the input and the state. The traditional approach to solve Francis-Byrnes-Isidori equations cannot be directly applied in this case since the interconnect matrix depends on the control input. Besides, even if this approach is well suited to the rejection of persistent disturbances, it shows the limits for the case of non-persistent disturbances which is also our object. Our contributed control method is realized through a cascade control structure based on the singular perturbation theory. The ultracapacitor current with the fastest motion rate is controlled in the inner fast loop through which we impose the desired dynamic to the system. The reduced system controlled in the outer slow loop is a Hamiltonian system and the controller is designed via interconnection and damping assignment. Simulations and experiments have been carried out to evaluate the control performance. A contrast of the system responses with and without the control algorithm shows that, with the control algorithm, the ultracapacitor effectively absorbs the disturbances; and verifies the effectiveness of the control algorithm

Texto completoAdvanced technologies are highly demanded in automotive industry to meet the more and more stringent regulations of fuel consumption. Cooptimization of design and control for vehicle propulsion systems with an enhanced computational efficiency is investigated in this thesis.Powertrain components, such as internal combustion engines, batteries, and electric motor/generators, are analytically modeled at descriptive and predictive level correspondingly for the development of fastrunning control optimization and for the scalability of design optimization. The minimal fuel consumption of a hybrid-electric vehicle is evaluated through novel optimization methods. These methods – including the Selective Hamiltonian Minimization, and the GRaphical-Analysis-Based energy Consumption Optimization – are able to evaluate the minimal energy consumption with the enhanced computational efficiency. In addition, the Fully-Analytic energy Consumption Evaluation method approximates the minimal energy consumption in closed form as a function of the mission characteristics and the design parameters of powertrain components.A few case studies are presented in details via the bi-level and uni-level co-optimization approaches, showing an effective improvement in the computational efficiency for the overall co-optimization process

This research has designed a new hybrid electric system, which is characterized by two mechanisms: internal combustion engine energy distribution mechanism and dual energy integration mechanism. The internal combustion engine energy distribution mechanism comprises first pulley set and second pulley set, whereby it’s possible to adjust its radius ratio and change the output load to road surface, output speed and corresponding load to maintain an optimal operating state of engine in a given generator rotational speed. In this way, engine energy can maintain the engine in an optimal state. For dual energy integration mechanism, any power source can be individually actuated by electric motor and the power transmitted from internal combustion engine energy distribution mechanism. Moreover, a one-way clutch can prevent the actuated power source from reversion, so any output power source will not be affected by another inactive power. Also, two input power sources can be integrated into a bigger power source via dual energy integration mechanism, thus resulting in twice the output energy and obtaining necessary tractive power. A dynamic equation is therefore derived from this system to obtain the flow direction of power source. Furthermore, dynamic equations of various system components can be established by modularized software Matlab/simulink, and fuzzy logic is used to control and develop this system’s dual energy integration mechanism as a control strategy. It can be learnt from system simulation that, after the engine energy is distributed by the controller of dual energy integration mechanism, subjected to deceleration ratio of first pulley set of internal combustion engine distribution mechanism and added to generator torque transmitted from second pulley set, the engine can maintain an optimum state under various operating conditions.

The single chip is electronic control unit (ECU) is used to integrate hybrid power control system. The hybrid power system is divided into two models: model one is pure motor driving, another driving model combine motor with engine. The design of the electronic control system of electronic control unit (ECU) is divided into two parts: one part is controller such as master controller、 exciting current controller、 engine speed controller, anther part is monitor, such as engine speed monitor and vehicle speed monitor. To verify the control strategies of the hybrid golf vehicle control system, the Fuzzy Logic Control is used to finish this simulation work. The implementation of the exciting current controller and engine speed controller are use P controller. The master controller and other controllers have many input signals, such as battery voltage、 throttle valve position、 engine speed. The output signals are stepper motor signal and exciting current signal. Finally, through the power integrate mechanism can integrate the motor power and engine power.

This research has designed study of energy management strategy of new parallel hybrid electric power system, which is characterized by the power integration distributing mechanism. When the electric motor and engine provide the power in the power integration distributing mechanism, the power source can provide power to the power integration distributing mechanism by oneself or at the same time. Moreover, a one-way clutch can prevent the actuated power source from reversion, so any output power source will not be affected by another inactive power. Also, two input power sources can be integrated into a bigger power source via the power integration distributing mechanism, thus resulting in twice the output energy and obtaining necessary the tractive power. A dynamic equation is therefore derived from this system to obtain the flow direction of power source. Furthermore, dynamic equations of various system components can be established by modularized software Matlab/simulink, and fuzzy logic is used to control and develop the energy management strategy of new parallel hybrid electric power system. It can be found from system simulation, the energy of the engine or the electric motor is controlled by the fuzzy logic. The electric motor and engine are adjustable to go to the best operating conditions by controller. The engine can maintain an optimum state under various operating conditions.

Transform of the conventional mini- or medium-size motorcycles into hybrid electric vehicles is very difficult, because their physical space is very limited and the cost of the hybrid power system is very high. Combine the advantages of internal combustion engine and electric motor, the parallel hybrid electric motorcycle systems have proved they can reduce emission, save energy and raise mileage. By using adaptable control strategy and complex electromechanical systems, a high performance and high efficiency hybrid electric vehicle with very low emission and very low energy consumption can be established. In this thesis, by using the energy management strategy, we have established and improved the performance of the driver and controller. Based on a digital signal processor (DSP), we have developed the energy management system for the new parallel hybrid electric system. The Li-ion battery management system has also developed in this thesis. On the other hand, under a real platform test, we verify and modify the performances of the energy management system. In addition, the energy management system controller adequately adjust the switch of battery and power unit to achieve the purpose of effectively manage the electric control system and make the internal combustion engine run at its sweet spot in most cases. Moreover, it also can robustly protect Li-ion battery no matter what operation modes are. The hybrid electric heavy motorcycle would have the merits of energy-saving. In addition, we also have installed a prototype of the hybrid electric heavy-duty motorcycle.

In a world where environment protection and energy conservation are growing concerns, the development of hybrid electric vehicles (HEV) has taken on an accelerated pace. We put our attention on the development and research of hybrid electric heavy motorcycle since it is much more widespread than HEV for individual transportation in Taiwan. Electrical control system in the thesis is mainly focused on the new parallel hybrid system; among them include car's using the instant battery charger, Li-ion battery management system (combined SMBus) and electrical control system main controller (combined DSP). In the motor control, by using the totally invariant variable structure system and linear matrix inequality theory, we design a modified output feedback controller. The controller using only output variable is proposed to stabilize the mismatched uncertainty system robustly that mismatched variable structure systems is asymptotically stable with good performance.

Two input power sources can be integrated into a powerful source via power integration and distribution mechanism, thus resulting in twice the output energy and obtaining necessary tractive power. In the dynamic simulation, the dynamic equations of whole new parallel hybrid electric power system can be established by using Matlab/simulink, and design the fuzzy logic controller of this system. The analysis and dynamic simulation of this new hybrid electric power system has been established in detail. It can be found by the way of dynamic simulation and energy management strategy, this fuzzy logic controller can be suitable to adjust two power sources of electric motor and internal combustion engine. The internal combustion engine can maintain an optimum state under various operating conditions. The change of each power source can also reach good operation and decrease the unnecessary power loss. The research results of this thesis have already completed a new set of low fuel consumption, low pollution and high performance hybrid electric power system.

There are still some bottleneck problems, which exit for the electric vehicles such as: mileage, charging…ect. All these problems seem not easily to be solved during the short time. Hybrid Electric Vehicle (HEV) becomes a transient solution. The HEV can use energy resources efficiency and reduce the pollution of the environment. But most HEV use lead-acid Battery on the world. We know lead-acid Battery has low output efficiency on heavy load immediately and easily causes power carry output delay. The purpose of this study is to solve this problem by hybrid battery systems. The main structure is that Li-ion Battery as secondary system and lead-acid battery as prime system to improve efficiency of output power under large-current discharge. We estimate the state of charge (SOC) of lead-acid battery and Li-ion battery in charge and discharge. By the experimental data, such as load voltage, discharge current, battery temperature, and the curve fitting technique, the equation of estimable state of charge of battery can be obtained. Through a series of experimental test, the simulations are demonstrated well efficiency and the feasibility of the proposed equations of SOC. Finally, we use LabVIEW to program manage system of Hybrid Electric Vehicle (HEV). Not only show state of charge of batteries to driver but also optimal control between Li-ion battery and Lead-acid Battery.

The generator and lithium battery management system plays an important role in many electromechanical devices. In a hybrid electric vehicles (HEV), the generator and lithium battery management system is not only the core unit of high performance but also the decisive unit of energy-conservation and reduce carbons. In this thesis, we develop an adaptive battery charge system and energy management strategy for HEV. They both cooperate with each other and turn into key unit of energy-conservation and reduce carbons. The adaptability battery charge system can immediately regulate optimum charge for lithium battery according to energy of power source. Based on this method, we design many suitable automation charge mode. It is able to charge the lithium battery on the condition of ultra-low energy source. Hence, it reaches these functions of improving the storing efficiency and reducing energy losses. Moreover, it can also equilibrium charge at the same time to lengthen the battery life. We will apply this adaptability battery charge system in the HEV platform. Because the power of generator and lithium battery is possible more than 10 kW, the circuit design and stability operation of this system are not an easy task. We consider power of generator modulation, charging and discharging reacting of lithium battery and safety norm to accomplish the adaptability battery charge system of HEV. Besides, we also achieved the construction of the prototype vehicle to real application and test in this research. Through the real experiments, we have proved the exactitude of theory and the practicability of the novel method. The adaptability battery charge system can not limits the application to the kind of particular battery and vehicle system, it can also apply to any kind of real-time electricity generation system of the frequently change energy.

With growing concerns over environmental protection and energy conservation, the hybrid electric vehicle (HEV) has taken center stage. The electric vehicle is a transportation implement of zero emission; however, its performance and driving distance are not acceptable in most cases. Thus the electric vehicle is not accepted extensively. On the other hand, the hybrid electric vehicle (HEV) not only achieves minimum fuel consumption and minimum emissions but also reduce pollution. The hybrid electric heavy motorcycle would have the merits of energy-saving. In this study investigates a new parallel hybrid electric heavy motorcycle, the aim of research is integral performance analysis and electrical control system. Its includes:(1) The simulation and performance analysis of integral systems: to simulate and analyze situations which the vehicle operate under variations of vehicle load; (2) Electrical control system: the major controller of the systems used by Digital Signal Processor (DSP) and control the vehicle under variations of driving pattern. In order to achieves minimum fuel consumption and minimum emissions, the internal combustion engine always operates at the sweet spot. The linear matrix inequality (LMI) method is applied in the design of dynamic output feedback controller for mismatched uncertain variable structure system (VSS). Using this new LMI theory based output feedback variable structure control (VSC), the mismatched variable structure systems is asymptotically stable with better performance. The electric control system and major controller of the hybrid electric vehicle have been achieved on the experimental platform. The prototype of hybrid vehicle is also established. The performances of the new hybrid electric vehicle are proved by experiment and operate actuality.

Texto completoFormal modelling is essential for precisely defining, understanding and reasoning when designing complex systems, such as cyberphysical systems. In this paper we present a formal specification using Event-B and Rodin platform for a case study of a cruise control system for a hybrid propulsion vehicle and electric bicycle (e-Bike). Our work uses the EventB method, a formal approach for reliable systems specification and verification, being supported by the Rodin platform, based on theorem proving, allowing a stepwise specification process based on refinement. We also use, from the same platform, the ProB model checker for the verification of the B-Machine and iUML plug-in to visualize our model. This approach shows the benefits of using a formal modelling platform, in the context of cyberphysical systems, which provides multiple ways of analysing a system.
