[Abstract]:This paper first introduces the development status, basic structure and working principle of switched reluctance linear motor, summarizes its characteristics and advantages, and describes the modeling and simulation methods and development tools. Then taking a three-phase switched reluctance linear motor as the research object, according to the size and material of the motor, the finite element analysis of the switched reluctance linear motor is carried out on the platform of Flux finite element analysis software. The flux / common energy-position-current characteristic data of the motor are obtained. Based on the basic physical equation of switched reluctance linear motor and the characteristic data obtained by Flux calculation, the nonlinear simulation models of switched reluctance linear motor and power generation system are built on the MATLAB/SIMULINK simulation platform. Then it introduces the hardware design of the hardware of the hardware-in-the-loop simulation using RT-LAB, including the motor body, controller, power converter, position detection and current and voltage detection. On this basis, the modeling process of RT-LAB hardware-in-the-loop simulation for switched reluctance linear motor and power generation control system is presented, and the closed-loop control of electric speed and generation voltage is realized. According to the principle of switched reluctance linear motor, the power generation control system adopts two power generation control methods, position sensor and no position sensor, to realize the position and no position generation operation of switched reluctance linear generator. Through the mathematical simulation and hardware-in-the-loop simulation of the switched reluctance linear motor (SRM), the velocity response curve and current waveform of the speed regulating system and the voltage and current waveforms of the power system are given. The results show that, Under the same condition, the mathematical simulation results agree with the corresponding hardware-in-the-loop simulation results, which verify the feasibility of the simulation model, and apply the established model to the traditional three-phase switched reluctance rotating motor. The validity of the model is further verified. Finally, the paper summarizes the work and gives the prospect of further work.
