[Abstract]:This paper mainly studies the embedded control system of switched reluctance motor (SRM). Firstly, the background and significance of the research are introduced. On the basis of analyzing the characteristics of current chopping control, voltage PWM control and angle position control of switched reluctance motor, the control scheme of embedded control system for switched reluctance motor is presented in this paper. The analysis and design of fuzzy regulator for speed control of switched reluctance motor are carried out. The power converter, drive circuit, position detection circuit and current detection circuit of switched reluctance motor control system are designed. The embedded controller of switched reluctance motor is designed based on DSP and FPGA. In the aspect of hardware, the DSP minimum system is designed, the position signal shaping and photoelectric isolating circuit, the output signal logic synthesis and photoelectric isolation circuit, and the communication circuit of upper computer are designed. The response delay of the position signal of the control circuit board is tested. The results show that both DSP and FPGA controllers can meet the control requirements of switched reluctance motor, and the speed of FPGA in logic processing is obviously better than that of DSP. Software: the embedded controller of switched reluctance motor based on DSP, the embedded frame has been fixed, the configuration of peripheral equipment and the development of control program are needed. The program flow chart is given in this paper, the embedded controller of switched reluctance motor based on FPGA, the embedded controller of switched reluctance motor based on FPGA, The embedded frame and function module are designed with HDL, and the control program of embedded microprocessor kernel MicroBlaze is developed by C language. On the platform of hardware and software designed in this paper, the speed regulation experiment of the embedded control system of switched reluctance motor is completed, and the experimental results are analyzed.
