Deskripsi
This paper, evaluate the effectiveness of a proposed speed loop pseudo derivative feedforward (PDFF) controller-based direct torque controller (DTC) for a PMSM drive against the performance of existing PI speed controller-based DTC and hysteresis current controller (HCC). The proposed PDFF-based speed regulator effectively reduces oscillation and overshoot associated with rotor angular speed, electromagnetic torque, and stator current. Two case studies, one using forward-to-reverse motoring operation and the other involving reverse-to-forward braking operation, has been validated to show the effectiveness of the proposed control strategy. The proposed controller's superior performance is demonstrated through experimental verification utilizing an FPGA controller for a 1.5 kW PMSM drive laboratory prototype.
