Analysis of Predictive Control Strategies for High-Speed Operation of PMSM Drive

Abstract

This work presents an analysis of predictive control strategies for a permanent magnet synchronous machine and designed initially at the nominal operating regimen. The moti-vation of this work is based on applications where high-speed requirement and limited supply voltage are needed such as pow-ered by battery-pack. Three control strategies are analyzed and compared based on the following characteristics: Model-Based Predictive Control, avoided weight factor, and fixed frequency operation. The main contribution of this work yields in the behavior verification of the mentioned control strategies and the availability determination to work along to the field-weakening approach. Moreover, a combination of two strategies is presented generating a new contribution; this combination reduces the operating time interval while reduces the computational burden. The effectiveness of the analysis is experimentally validated.
