A SIMPLIFIED TWO-SWITCHING-BASED MODEL-FREE PREDICTIVE CURRENT CONTROLLER FOR AN INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE SYSTEM
This paper presents a simplified two-switching-based modelfree predictive current control (STSB-MFPCC) method as well as its application to interior permanent magnet synchronous motor (IPMSM) drive systems. Unlike existing model predictive current controller (MPCC) that uses 7 basic voltage vectors, STSB-MFPCC employs 19 synthesized ones, with each of which consisting of two basic voltage vectors. The new method does not require any information about the load parameters, back electromotive force, nor the system model. Compared to modelbased controllers, the proposed one has a distinctive and appealing nature in that it is much less sensitive to system parameter variations. A digital signal controller, TMS320F28377S, is used to realize and validate the new method and verifies its feasibility as well as performance saliency
