Against the existing poor dynamic performance, difficult to adjusting parameters of the controllers issue in PMSMs vector control system, based on the PMSM's dq rotating coordinate model, an inverse system model of PMSM is deduced. And a pseudo linear system realizing the decoupling of the d-axis current and mechanical velocity is constructed. By synthesizing the pseudo linear system, a sliding mode variable structure controller is proposed. In order to estimate rotor's position and speed, a reduced order observer for back electromotive force is proposed. At last some simulations are proceeded to verify the proposed system's performance. The simulation results show that the control strategy mentioned in this paper has good dynamics, steady state performance. Rotors position and speed can be accurately estimated by the proposed method.

Sliding Mode Variable Structure

In this paper, according to the induction motor in rotating coordinate system mathematical model, established based on rotor flux oriented vector control model and realized flux linkage and torque decoupling. In order to solve the current high coupling, designed the sliding mode variable structure control algorithm of current controller. Based on the sliding mode variable structure control algorithm achievable conditions and Lyapunov stability theorem, proved that the sliding mode of accessibility and stability, determined the sliding model parameters. The simulation results show that the sliding mode variable structure control of induction motor vector control system, can reduce the torque ripple and the speed overshoot and improve the system parameter perturbation and external disturbance signal robustness.
