Super-Twisting Sliding Mode Control with SVR Disturbance Observer for PMSM Speed Regulation

Sliding mode control and disturbance compensation techniques are applied to a nonlinear speed algorithm for permanent magnet synchronous motor (PMSM). Optimizing the performance of PMSM systems with various disturbances uncertainties is challenging. To achieve satisfactory performance, sliding method based on super-twisting reaching law (STRL) presented. STRL can adapt dynamically variations controlled system. The maintains high tracking controller allows input eliminate chattering. estimate compensate disturbances, support vector regression-disturbance observer (SVR-DOB) estimated were used minimize modeling errors improve rejection. A using SVR-DOB achieves precision, simulation results demonstrated validity proposed approach.
