Synchronous Reluctance Motors Torque Ripples Reduction using Feedback Cascaded P-I-I Controller

Synchronous Reluctance Motors (SynRMs) -or Reluctance Synchronous Motors (RSMs)- have recently become an important component of the electric vehicles' (EVs) industry when it used as a variable speed AC drives, due to its excellent features of high ratio of power to weight and torque to current, high efficiency and ruggedness. One of the major SynRMs' problems is the Torque Ripples (TRs). In this paper and to mitigate or minimize these TRs, a feedback cascaded p-I-I controller is used and worked as an Active Ripple Filter. Simulation results showed its effectiveness in TRs minimization.
