【 摘 要 】

This paper is concerned with velocity control in a permanent magnet synchronous motor (PMSM) when it is fed by an inverter-DC/DC Buck power converter system as power amplifier. We present, for the first time, a formal local asymptotic stability proof to solve this control problem. We stress that this is the first time that this problem is solved for an AC motor. Our control scheme is simple when compared to differential flatness- and backsteping-based proposals in the literature to solve this problem for DC motors. The key for these achievements is the employment of a novel passivity-based approach which takes advantage of the natural energy exchange among the electrical and mechanical subsystems that compose the inverter-DC/DC Buck power converter-PMSM system. The main features of this novel passivity-based approach are summarized in this paper.
