Multiphase Robust Position Control Scheme for Synchronous Reluctance Motor

In the recent years the synchronous reluctance motor (SynRM) has received much attention due to its desirable controllability and simple structure. In this paper, in order to improve the position control performance of a three phase SynRM, a control scheme is proposed. In the proposed controller design, the smooth operation of the traditional linear controllers and the robustness of variable structure controllers have been considered. The proposed controller eliminates the drawbacks of traditional linear control schemes and conventional variable structure control scheme, such as high frequency chattering at the same time. Yet, their advantages such as smooth operation and robustness are preserved as a big merit. The experimental results clearly demonstrate the superiority of the proposed controller over conventional control schemes. © 2015, © Institution of Engineers, Australia.
