摘要
设计了一种应用于五相永磁容错电机的解耦控制器,实现了调速系统的线性化及解耦。该智能控制器采用支持向量机(SVM)逆系统理论结合构成SVM逆控制器,由SVM来逼近原系统的逆系统,将原系统解耦成两个伪线性子系统,通过两个PI控制器调节子系统的控制性能。SVM逆控制器集合了SVM方法的高精度跟踪与逆系统解耦的优点。仿真和实验结果表明,在FTPM电机运行时,当参数发生变化,SVM逆系统控制器依然能表现出很好的稳定性与精确的响应性。
A decoupling controller for five-phase fault-tolerant permanent-magnet motor drives is proposed to linearize and decouple the speed regulation system. The proposed intelligent controller adopts support vector machine（ SVM） and inverse system theory,in which SVM is used to approach the inverse system of the original system,then the original system is to two pseudo-linear systems. Moreover,the two PI controllers are applied to adjust the performance of the proposed controller. The simulated and experimental results show that the proposed SVM inverse controller offers good stability and precise response regardless of the system parameter changes.
