Wide speed operation exploitation of sinusoidal permanent magnet motors

A novel predictive control algorithm, for drives including sinusoidal permanent magnet motor is proposed in this paper. It is based on the instantaneous values mathematical model of the machine, and allows to exploit the drive performances both in steady-state and in transient operations, by fully satisfying the instantaneous voltage and current constraints. The algorithm validation has been performed by means of experiment analysis. The results show an improvement of the dynamic performances achieved with the proposed control, thanks to a very low ripple of the machine output torque.
