Abstract

High-performance position sensorless control requires accurate motor phase voltages in the entire speed range, especially in zero-speed and low-speed regions. Inverter nonlinearity has been becoming a main barrier restricting the development of PMSM sensorless, it is essential to eliminate the effect of inverter nonlinearity on the overall control scheme. This paper proposed a universal compensator by combing a proportional integral resonant controller and Luenberger observer. Compared with other compensators, the proposed compensator can be directly utilized in PMSM control scheme under different PMSM speeds. In addition, the theoretical analysis and parameter tuning guideline are firstly elaborated. In order to verify the effectiveness and correctness of the proposed controller, relevant experiments of the proposed approach are carried out in this paper.
