The poor robustness of current loop parameters is the main factor restricting the traditional Model Predictive Current Control(MPCC)from becoming a high-performance control method.Among various improvement methods for this issue,Incremental Model Predictive Current Control(IMPCC)have become a research hotspot as a simple and feasible method for eliminating magnetic flux.On this basis,a parameter adaptive incremental model based MPCC(PAIMPCC)is proposed.Unlike other incremental model-based methods,this method takes the prediction error of IMPCC as the objective function and combines Finite time Gradient Descent(FGD)to adaptively update the inductance in real time,achieving robustness to all parameters.
