[Abstract]:In this paper, the control system of switched reluctance motor for vehicle is studied, and the development of the drive system of electric vehicle is summarized and analyzed. The advantages and disadvantages of several motor drive control systems which are widely used at present are analyzed and compared. The composition of the drive control system of the switched reluctance motor and the characteristics of the switched reluctance motor are introduced. The main circuit, driving circuit and position detecting circuit of switched reluctance motor are designed. Based on the analysis of three basic control methods, current chopping, voltage chopping and angle control of switched reluctance motor, three different control methods are proposed in the low speed, middle speed and high speed stages. In order to improve the efficiency, changing the turn-on angle and turn-off angle on line is the control strategy of switched reluctance motor (SRM). The controller with dsPIC30F6010A as the core is designed. In the aspect of hardware, the detection circuit of voltage, current and temperature, the output circuit of logic signal and the keyboard display circuit are designed. In terms of software, the main program and subroutine flow chart are designed based on the dsPIC30F6010A controller of switched reluctance motor and the proposed wide range speed control strategy, and the corresponding control program is developed and debugged by C language. Through the experiment of the 7.5kW switched reluctance motor control platform and the comparison and analysis of the velocity waveform and the current waveform of different speed section, it is verified that the three-segment wide range speed control method has good start and acceleration. Deceleration performance, very suitable for the application of electric vehicles. Finally, the paper summarizes the work and points out the direction of the next work.
