The goal is to improve system performance under variable speeds and loads. Various control methods, including vector control and SMC, were evaluated through simulations. Results confirm the dynamic advantages of the hybrid fuzzy controller in enhancing speed, torque, and flux regulation.enDFIMPISMCFUZZYVECTOR CONTROL.Thesis
