Lyapunov Redesign 을 통한 PMSM 제어기 설계

Abstract

In this paper, we present a nonlinear torque modulation and current controller based on Lyapunov redesign in the stationary reference frame ( α , β ) and analysis of a velocity tracking performance caused by the phase current tracking errors of Permanent Magnetic Synchronous Motors(PMSMs). Using the proposed control method ensures uniform boundedness of phase current tracking errors in a finite time so that the motion tracking error converges exponentially to a small bounded ball 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.
