Digital vector control of a six-phase series-connected two-motor drive

This paper deals with a decoupled vector control a six-phase series-connected two-motor drive using the RST controller. This kind of controller is a various of digital controller. The first step is the choice of a reference model of the current and speed loops. Then, the three polynomials R, S, T constituting the controllers will be synthesized by utilizing the Diophante equation after introducing some specifications on each polynomial. Experimental results show the effectiveness of the study.
