摘　　要：以三相12/8极开关磁阻电机作为研究对象,设计了以TMS320F28335芯片作为主控单元的开关磁阻电机调速系统。调速系统由软件部分和硬件部分组成。软件部分采用双闭环PI进行控制,电流为内环,转速为外环,在综合考虑速度给定信号、位置信号、保护信号的基础上,计算得出对应导通相的PWM驱动信号;硬件部分主要由开关磁阻电机、功率变换器、电流检测、位置检测、键盘和数码管显示屏组成。结合位置信号、速度信号、电流反馈信号,对开关磁阻电机的控制策略进行调整,让其在电压斩波控制方式下工作。经过参数调整实验,最后选择合理的PI控制比例系数和积分系数。通过实验数据优化、对比、分析,验证了此控制系统设计的合理性。Taking the three-phase 12/8 pole switched reluctance motor as the research object, the speed control system of the switched reluctance motor with the chip of TMS320 F28335 as the main control unit is designed. The speed regulation system consists of software and hardware. The double closed-loop PI is used to control in the software part where the current is the inner loop and the speed is the outer loop. Based on the given speed signal, position signal and guard signal, the PWM driving signal corresponding to the conducting phase is calculated. The hardware part is primarily composed of switched reluctance motor, power converter, current detection, position detection, keyboard and LED segment display. Given a combination of position signal, speed signal and current feedback signal, the control strategy of switched reluctance motor is adjusted to work under voltage chopper control mode. After parameter adjustment experiment is completed, the reasonable proportional and integral coefficients of PI controller are selected. The rationality of the design of the control system is verified by the optimization, comparison and analysis of the experimental data.
