Approach for classifying direct pcs applied to ac motor drives

Abstract

So far, various categorisations have been proposed for segregating predictive controllers (PCs). However, these categorisations have some shortcomings which lead to improper segregation of PCs. In this study, a new categorisation is proposed for more precise segregation of PCs applied to AC motor drives. In this categorisation, PCs are categorised based on existence or the absence of a cost function, number of voltage vectors applied to motor in each control cycle, and prediction horizon. Basic concepts, operating principles, and important characteristics of each category are explained in depth. Moreover, the advantages and disadvantages of each category are identified by conducting various experimental tests. © The Institution of Engineering and Technology 2018.
