A non-linear backstepping control of Permanent Magnet Synchronous Motor (PMSM)

In the industry, permanent magnet synchronous motors are one of most widely used and have superior performance compared to other types motors. The principal objective this paper is ameliorate PMSMs by implementing a robust non-linear backstepping control. first part deals with vector control mechanical sensors using PI controller. second part, we shed light on control, Lyapunov function, PMSM from point view stability robustness. results validated MALTAB/SIMULINK. obtained show good dynamic PMSM’s controller, also very sensitive parameter’s machine variation
