Abstract

This paper proposes a novel controller design for a sensorless PMSM drive system, which is fed by a matrix converter. In this paper, first, a rotor position estimating technique is proposed to obtain the shaft angle of the motor. Next, a two-degree-of-freedom PI controller, including a forward-loop controller and a load compensator, is proposed to improve the performance of the system. The whole drive system has satisfactory transient responses and load disturbance rejection abilities. In addition, the parameters of the PI controller are calculated by using a frequency-domain parameter optimization technique. Only simple algebraic computation is required. Finally, a 32-bit TMS320C40 digital signal processor is used to execute the sensorless technique and all of the control loops, including a current-loop and a speed-loop. Several experimental results are shown to validate the theoretical analysis.
