摘要: 为了提高永磁同步电机(PMSM)控制系统的控制性能,设计了一种混合H2/H∞控制器。通过混合灵敏度方法设计系统的H∞次优控制器,采用粒子群优化(PSO)算法选取H2性能指标最小的控制器,从而得到混合H2/H∞控制器。采用仿真对所设计控制器的性能与比例积分(PI)控制器进行了对比测试,测试结果证明了混合H2/H∞控制器具有比PI控制器更好的控制效果,同时也表明采用PSO算法进行控制器设计是有效、可行的。

Abstract: A mixed H2/H∞ robust controller was designed to enhance the performances of Permanent Magnet Synchronous Motor (PMSM) control system. Firstly, the H∞ suboptimal controllers were designed with mixed sensitivity method. Then the controller with the best H2 performance standard was selected with Particle Swarm Optimization (PSO) and the H2/H∞ robust controller was obtained. Finally, the capability of mixed H2/H∞ controller was verified with simulation. The results indicate that the robust controller has better performance compared with traditional Proportional Integral (PI) controller, and the PSO algorithm is proved valid for the design of H2/H∞ controller in addition.
