A cascade MPC control structure for a PMSM with speed ripple minimization

Abstract

This paper addresses the problem of reducing the impact of periodic disturbances arising from the current sensor offset error on the speed control of a permanent-magnet synchronous motor. The new results are based on a cascade model predictive control scheme with an embedded disturbance model. Supporting experimental results, where the per-unit model is used to improve numerical conditioning, are also given. © 1982-2012 IEEE.
