Super-Twisting Sliding 기법을 이용한 PMSM 외란 관측기 설계

Abstract

In this paper, we present a disturbance estimation technique with supwer-twisting sliding extended state observer and compensation logics in the stationary reference frame ( α , β ) of Permanent Magnetic Synchronous Motors(PMSMs). Using the proposed method ensures uniform boundedness of estimation error of external disturbances in a finite time. With AMESim and MATLAB/Simulink, we validated the torque modulation and nonlinear controller with a topological model which includes a 3-phase PWM inverter and PMSM motor provided in AMESim.
