基于模糊滑模控制的容错系统伺服控制器设计

六相永磁容错电机因故障需缺相运行时,传统的控制方式要改变控制器和剩余相电流,系统才能正常运行.基于模糊切换增益调节的滑模控制,为该电机驱动的电力作动系统设计了一个伺服控制器.该控制器允许电机模型不精确,电机缺相运行时,无需改变控制器参数,而只需改变各相电流的幅值和相位.仿真结果表明,系统正常运行时性能良好;缺相运行时,不改变控制器参数,系统保持正常状态的性能.

Design of Servo Controller of Fault Tolerant System Based on Fuzzy Sliding Control

If the six-phase permanent magnet fault tolerant motor is controlled with traditional method,both the controller and current flows of the remained phases should be changed,can the system operate normal,when the motor operates default phase because of failure. This paper designs a servo controller,which is based on fuzzy sliding control and don't need exactitude model,for an electrical actuator system driven by the motor. The controller needn't be changed,but only the current flows of the remained phases are...
