摘要：

Aiming at the slow dynamic response and the chattering problem from conventional exponential reaching law sliding mode applied in permanent magnet synchronous motor vector control in current loop, firstly this paper used weighted integral type sliding mode control algorithm to design the current loop controller. For the second step, the stability of the system was proved with lyapunov stability theory. Simulation results show that current controller of vector control system based on weighted integral gain sliding mode has strong robustness to parameter perturbation and external disturbance compared with traditional sliding mode control, and improves system's dynamic response and control precision. © Yi et al.
