Abstract:
A sliding mode variable structure speed controller was proposed for surface permanent magnet synchronous motor in order to overcome the drawback of conventional PID speed controller,to effectively curb the state variables of overshoot problems,to speed up the convergence speed of the rotor,and to en-hance the anti-interference of the system. Unlike conventional PID speed controller,the controller associ-ated speed error with the quantity of system state. The load torque values is real-time controlled by the default upper and lower bounds sliding mode variable structure controller. It can replace the conventional PID controller with the applications to the permanent magnet synchronous motor vector control system. Simulation and experimental results show that sliding mode variable structure controller based on the up-per and lower bounds can effectively improve the static and dynamic characteristics and robustness of the system.
