Abstract :
A current control scheme based on the decoupling of the motor back EMF voltage and a deadbeat feedback control to achieve fast dynamic response on the motor current is proposed in this paper. Since the de-coupling voltage is expressed as a function of motor current and control voltage, the scheme is simple for microprocessor implementation and is not sensitive to the motor parameters and the tuning of the field orientation control. The performance of the proposed control scheme was investigated both by simulation and experiment, good static and dynamic performances have been obtained in the experimental verifications
