对无刷永磁容错电机结构的容错原理进行分析，对空间矢量控制(SVPWM)的原理及其控制策略、具体IGBT驱动信号产生方法进行详细分析，并设计了基于dsPIC30f4011的硬件矢量控制系统。此外，基于MPLAB IDE集成开发环境，在软件上实现了速度闭环和双电流闭环控制。硬件实验的空载和带负载情况下的调速和稳定运行也证明了方案的可行性。通过Matlab软件，对以上理论和控制方法进行详细仿真论述，验证了方案的正确性。本文侧重从理论和仿真的角度对该系统进行分析。The structure’s advantage about fault tolerance of FT-PMM was analyzed in detail. The hardware of vector control system based on the principle of SVPWM and its special control strategy were designed. The dsPIC30f4011 was chosen as the control chip. The generating principle of drive signals was described. The control loop of speed and dual current was realized in MPLAB IDE Integrated Development Environment. The theory was proved right by Matlab simulation and the simulation process of theory and control method was described in detail in this paper. Finally, the result of hardware test verified that the speed control and stable operation of this system were feasible.
