This paper presents a robust Linear parameter-varying controller (LPV) in the Reference Signal Tracking (RST) structure to the speed control of a Switched Reluctance Motor (SRM) 6/4. This machine has a simulator that considers the non-linearities present in the MRV operation. The dynamics of the speed loop was based on an ARX LPV model identified for a range of operation from data collected in simulation, where the scheduling parameter was the normalized filtered current level. With the model parameters, the LPV controller parameters were determined by means of a convex optimization problem, in the form of a parameterized LMI (PLMI). Thus, the performance of the LPV controller subjected to the variation of the scheduling parameters was compared to conventional controllers with fixed parameters.
