access icon free Hybrid exploration state for the simplified finite control set-model predictive control with a deadbeat solution for reducing the current ripple in permanent magnet synchronous motor

This research tends to provide a novel exploration state for finite control set-model predictive control. The aim of this study is to reduce the line current ripple at a given average switching frequency. The proposed method with hybrid exploration state divides the space vector plane into two regions. Each conventional exploration state is applied to a region, which would result in a lower root mean square current ripple. The above-mentioned procedure is based on the calculation of the stator flux ripple in the stationary reference frame during the sampling time. Consequently, a simple expression based on the magnitude and the phase angle of the reference voltage vector will be obtained, which can be employed as a measure for the current ripple. The superior performance of the proposed method over the conventional exploration state methods is verified by the theoretical results and the experimental tests.
