A current control technique for a permanent magnet synchronous motor (PMSM) with a simple disturbance estimation scheme is proposed. Among the various current control schemes for a PMSM drive, the predictive control is known to give a superior performance. This scheme, however, requires the full knowledge of motor parameters. To overcome such a limitation, the disturbances caused by the parameter variations will be estimated by using a disturbance observer theory and used for the calculation of the reference voltages by a feedforward control. Thus, the control performance can be significantly improved with a relatively simple control algorithm. The proposed control scheme is implemented on a PMSM using DSP TMS320C30 and the effectiveness is verified through the comparative experiments.
