Self-commissioning method of flux linkage for synchronous reluctance motor based on bipolar voltage injection and PSO fitting
The synchronous reluctance motor (SynRM) exhibits significant flux saturation phenomenon.If a fixed inductance value is used in the motor control algorithm,it cannot achieve the desired control performance.To ad-dress this issue,a flux self-commissioning method is proposed.Firstly,the cross-saturation phenomenon of SynRM is analyzed in detail,and a flux saturation model of SynRM is established using the constant speed method.Then,a self-commissioning reference method with bipolar voltage injection is designed.The raw flux data with uneven dis-tribution is post-processed by fitting flux curves in different regions,and the coefficients of the fitting function are obtained using the particle swarm optimization (PSO) algorithm.Finally,the proposed flux self-commissioning strategy is validated on an experimental platform.The results show that compared to direct interpolation methods,the post-processing method of fitting flux curves in different regions does not require a specific distribution of the raw data points,thus significantly reducing the error of the flux surface.
