Robust Current Predictive Control of Synchronous Reluctance Machines Considering Magnetic Saturation

In this article, the magnetic saturation effect of synchronous reluctance motor is considered for mathematical modelling. Based on this, deadbeat model predictive control is applied to synchronous reluctance motors, introducing the concepts of dynamic inductance and apparent inductance. Due to the mismatch between the nominal value and the actual value due to material aging, temperature change or measurement error during the application process, this paper analyses the impact of the mismatch of each parameter on the predictive control performance and proposed a robust current predictive control method. The robustness of the system is improved with little change in the original control structure
