Differential flatness based speed/torque control with state-observers of permanent magnet synchronous motor drives

This paper introduces a nonlinear control scheme based on the differential flatness approach for controlling the speed/torque of a permanent magnet synchronous motor (PMSM) drive. The differential flatness estimation is a model based approach. Then, two state-observers are proposed to estimate a load torque disturbance and a stator resistance (represent… CONTINUE READING
