In this paper a novel hysteresis current control is proposed. It is based on a simplified predictive algorithm that somewhat recalls those used in the direct torque control drives. The two major features are the sensible reduction of inverter switches commutations and the full-digital implementation based on look-up tables. The proposed algorithm has been implemented as inner loop of a speed control for a permanent magnet synchronous motor (PMSM).

Abstract

In this paper a novel hysteresis current control is proposed. It is based on a simplified predictive algorithm that somewhat recalls those used in the direct torque control drives. The two major features are the sensible reduction of inverter switches commutations and the full-digital implementation based on look-up tables. The proposed algorithm has been implemented as inner loop of a speed control for a permanent magnet synchronous motor (PMSM). The result has been a low-cost, efficient and reliable PMSM drive, with good overall dynamic performance. The paper reports both simulation and experimental results, carried out on a laboratory prototype.
