Sliding mode Controller Based on the Second-Order Model of PMSM Speed Regulation System
For the permanent magnetic synchronous motor (PMSM) speed regulation system based on vector control and double closed loops, the speed controller is usually designed by considering the speed output equation as a first order case. This design employs the output of the speed regulator, i.e., the input of the current regulator, to approximately replace the real q-axis stator current. The regular controller can not compensate this kind of approximation, which makes it difficult to obtain excellent performance for the speed regulation system. Considering this problem, we analyze the second-order model of the PMSM speed regulation system. Based on this model, we design a corresponding sliding model controller. This speed controller is easy to deduce and realize. The experiment results indicate that under this scheme the speed regulation system can have a stronger anti-disturbance ability and a less overshoot.
