Abstract

Current regulation in salient PMSM drives is essential to the overall drive performance. Various controller design methods are commonly implemented in the literature. Many of these methods could be represented as a special case of a generalized 2DOF PI controller. In this paper, an improved design based on 2DOF PI is presented. The controller has an improved reference tracking, disturbance rejection and robustness compared to existing designs. For a desired bandwidth, the controller could be designed using pole-placement method. The design is robust against any uncertainty or variation in the machine parameters. Simulation results verified the performance and robustness of the proposed design. A 1 kW motor drive is used to validate the design experimentally.
