Pełny tekst źródłaThesis for the degree of Doctor of Engineering in specialty 05.22.09 "Electric transport " - National Technical University "Kharkiv Polytechnic Institute" MES of Ukraine, Kharkov, 2018. The thesis is devoted to the creation of scientific foundations for the selection of optimal parameters and operating modes for cooling systems for asynchronous traction motors of electric transport. An algorithm for solving the Hamilton-Jacobi-Bellman equation for the problem of the motion of an electric stock on a section of a track with a given profile and a traffic schedule is developed. That makes it possible to create an expert control system for motion. Features of this algorithm is the use of penalty functions to describe the restrictions imposed by the traffic schedule: the train reaches the destination point for a given driving time, the speed limit on the sections of the track, and the absence of train idle time during the movement. A single approach to penalty functions is also applied to introduce constraints on the adhesion. This approach allows to reduce significantly the costs of the estimated time and to simplify the procedures for calculating energy costs. A mathematical model is created to determine the efficiency of the traction drive. The model includes the determination of the main losses in an asynchronous traction motor, taking into account the saturation of the magnetic system, which is determined by the results of solving a recurrent nonlinear equation. Also, the model takes into account losses from higher harmonic stresses in copper and steel, mechanical and additional losses. The developed model takes into account static and dynamic losses in IGBT transistors and diodes of a semiconductor converter. A method for optimizing the parameters and operating modes of cooling systems for asynchronous traction motors of the electric stock is developed. It consists of the following main stages: determination of the optimum mode of the traction drive operation on the basis of the proposed expression of its efficiency; determination of optimum modes of movement of the electric stock by the criterion of minimum costs; solution of the traction problem of motion on a section of the track with a specified traffic schedule and the track profile, as well as the determination of the dependence of the change in losses in the elements of asynchronous traction engines in time; choice of parameters and operation modes of cooling systems for asynchronous traction motors, which determine the efficiency of the cooling and ventilation system of the electric stock; solution of the problem of relative minimization of the cooling system for asynchronous traction motors with a modernized criterion of economic efficiency based on the Weil method on the generalized golden section and the problem of analyzing the ventilation and cooling system of traction motors, which is based on the mathematical model of thermal motor conditions by the generalized equivalent thermal scheme.

The paper proposed the development and traction control system (TCS) of a front-wheel drive electric vehicle (EV). Two in-wheel motors were utilized in the system to construct a power-scattered EV. The permanent magnet servo motor can individually control the motor power output and immediately limit the torque individual. This paper imposed the maximum transmission torque estimation (MTTE) system as the core of TCS for preventing the vehicle skid. The control algorithm is embedded in a high speed microprocessor, which can real-timely monitor feedback signals. In the torqure ouput, a plenary gearbox was employed to amplify the motor torque. This paper also used the simulation software “CarSim” to analyze the anti-skid performace of the prototype EV which is called Corsa-EV. The crucial issues include vehicle dynamics construction and anti-skid evaluation. From the results of simulation, it is obvious that the propsed EV can achieve an accetptable performance of stability and safety with the enhancement of MTTE.

Pełny tekst źródłaA hydromechanical traction system for a wheeled vehicle is being examined in order to generate information that will be applicable to the design of the drive system controller. The functional analysis of the drive system leads to the description of the system and component properties. A design methodology is proposed by which the system components could be dimensioned and the system layout constructed by taking into account the specified functional requirements concerning the system performance. An explicit description of power flow and manipulation of power flow in the drive system is given. The mechanisms by which the hydraulic machines are adjusted to manipulate power flow, are examined in detail so that their contribution to the dynamic behaviour of the total drive system can be described. , Experimental measurements are used to obtain a reliable description of the dynamic response of the adjustment mechanisms. An analytical model of the dynamic behaviour of the drive system is presented in block diagram format. The inherent multiple-input-multiple-output characteristic of the drive system with secondary controlled hydraulic motors is discussed. The block diagram is simplified to create linearized transfer functions that will depict the input-output-relationships. The effect of an accumulator on the dynamic response of the system is also given. Digital simulation programmes are constructed from the analytical model. The requirements of a vehicle traction system are interpreted and used as guidelines to conduct a functional design of the control system layout. The delivery of torque and the restriction of wheel spin for each of the wheel drive units, which is realised by secondary controlled hydraulic motors, are described in detail. A hypothetical drive system is considered and quantitive control system design information is generated, using the simulation programmes. Some aspects of the dynamic response of the system are discussed and it is shown that the adjustment mechanism has a big influence on the overall dynamic response of the system.

The traction force control of electric wheel is related to the parameters of DC motor, this research connects DC motor to loading motor using shaft-to-shaft in-line placement and we precisely measure the changing behavior of DC motor under the various command of loading motor. As for building the Database of DC motor, we record the relationship between current, RPM and traction force under above circumstances. We use loading motor to output the different traction force simulation under the pattern of various road surfaces, these can provide information for the control of DC motor’s traction force. Our research focus on the relationship between the characteristic of DC motor and traction force, discussing DC motor’s characteristic and mechanics control ability under the condition of different road surfaces. We summarize and analyze DC motor correlated theories, for instance, we build relative relation between DC motor’s electrical signal and traction force, and build Database through actual measurement. Finally, we implement Control law and Control logic in driven single wheel of DC motor through the platform of actual testing, verifying correlated theories and control strategy for the enhancement of vehicle’s safety, stability and controllability.

This paper proposes an approach to evaluate and control the traction force of the vehicle wheels driven by DC motors directly without monitoring the slip ratio of the wheel. Utilizing the built character database of the DC motor, or so-called force-RPM-current database, a gain-scheduled approach is developed to provide the appropriate traction force while one traction wheel of the vehicle is traveling into different road surface. An illustrated simulation with a scenario close to real situation is also given to show the feasibility to evaluate and control the traction force through the database of the DC motor.
