Model Predictive Control with Reduced Integration Step Size for Continuous Control of an IPM Motor

This paper presents an approach to continuous control set model predictive control, which uses reduced integration step size. The reduced integration step size allows to obtain a stream of finite control set, which can be filtered in order to obtain continuous control set. The Sinc-filter can be used to obtain improved accuracy of the voltage references. This approach is suitable for the motors with the high nonlinearity of the magnetization curve, which can be taken into account. The simulation results are presented in case of interior permanent magnet motor.
