Abstract :
This paper proposes a new control algorithm for a matrix converter PMSM position control system. First, a new switching strategy is proposed to reduce the current harmonics of the permanent magnet synchronous motor. Next, a two-degree-of-freedom controller is proposed to improve the system performance. The parameters of this controller are obtained by using frequency-domain optimization technique. The controller design procedures require only algebraic computation. In addition, the realization of the controller is very simple. All the control loops, including current-loop, speed-loop, and position-loop, are implemented by a 32-bit TMS320C40 digital signal processor. The hardware, therefore, is very simple. Several experimental results are shown to validate the theoretical analysis
