摘　　要：为了实现五相感应电机驱动系统容错运行,首先需要快速检测和定位系统开关故障。对此,设计一种基于模型预测控制器的故障诊断算法。传统的电机驱动系统故障检测技术是基于磁场定向控制器和旋转坐标变换,对于性能更优的模型预测控制则无法实施。新方案根据矢量空间分解原理设计,从根本上革新了传统故障检测机制,并以较小的计算负担,快速地检出故障。同时该方案易于扩展到其他多相电机。利用五相感应电机驱动实验平台对新型故障诊断策略进行了测试。研究结果表明,新型故障诊断方案对故障的快速检测实现了控制器故障容错运行切换。In order to realize the fault-tolerant operation of the five-phase induction motor driving system,it is first necessary to quickly detect and locate the system switch fault.Therefore,a fault diagnosis algorithm based on model predictive controller was designed.The traditional motor driving system fault detection technology is based on the field oriented controller and the rotating coordinate transformation,and the model predictive control with better performance cannot be implemented.The new scheme was designed according to the principle of vector space decomposition,which fundamentally revolutionizes the traditional fault detection mechanism and quickly detects faults with a small computational burden.At the same time,the solution is easy to extend to other multiphase motors.The new fault diagnosis strategy was tested using a five-phase induction motor driven test platform.The research results show that the fault diagnosis of the new fault diagnosis scheme realizes fault-tolerant operation switching of the controller fault.
