Abstract

This paper presents a novel algorithm to eliminate d-q axis static current error of PMSM predictive current control when the model in predictive controller has parameter mismatch with real system. The relationship between current error and parameter mismatch is analyzed numerically, and the static current error is eliminated by introducing current error integration in d-axis current control while dynamically adjusting the parameter of controller flux according to the q-axis current error. The algorithm is quite suitable for industrial application and is verified through simulation and experiment on a 3.3kW PMSM servo platform.
