电动汽车用SRM数字化驱动系统的硬件实现

The design of a SRM hardware drive system for electric vehicles

设计了以DSP为主控制器的电动汽车用SRM(开关磁阻电机)数字化驱动系统,采用最新的转矩矢量控制策略,给出了系统硬件电路的具体结构。仿真及实验结果表明:该系统硬件简单、实用性好、具有良好的动态和静态特性,有效地抑制了转矩脉动。

A SRM（ Switched Reluctance Motor） drive system used in electric vehicles is designed, which utilized DSP as main controller. The novel torque vector control strategy is adopted in this paper. The hardware circuit is presented in detail. The result from simulation and experiment show that this system possesses advantages of simple hardware, good real-time with dynamic and static characteristic, it can effectively reduce the torque ripple.
