Simulation of Permanent Magnet Synchronous Motor Vector Control Based on Power Law of Approach

In recent years, the development of emerging fields has received more attention. such as: Unmanned aerial vehicle (uav), new energy, electric vehicles, robots, etc. so as also drive their motor's researchers attention, motor control performance will directly affect the characteristics of the industrial control system, the permanent magnet synchronous motor and stand out with its own merits, permanent magnet synchronous motor is a nonlinear and strong coupling system, When the internal control systems affected by external disturbances or motor parameter changes, the traditional PI control can not meet the actual demand, therefore in order to improve the dynamic performance of the permanent magnet synchronous motor vector control system, based on the sliding mode theory, a power law of approach sliding mode controller is proposed to replace PI controller to improve the efficiency of system control, The feasibility of this method is proved in Simulink.
