Abstract

In this paper, we present a load torque estimation/compensation technique for a Permanent Magnet Synchronous Motor system (PMSMs) in a stationary reference frame (α, β). Using the proposed estimation/control method ensures uniform boundedness of an angular velocity tracking error in a finite time. With the experimental validation results, which include a 3-phase PWM inverter and PMSM motor, we show the effectiveness of the proposed method.
