“…I N industrial applications, induction motors are well known for their reliability, minimal maintenance and low cost. At present, induction motors have extensive applications ranging from speed motion control systems to highlevel control, including punching presses, compressors, elevators, centrifugal pumps and so forth [1], [2]. A highperformance modern electrical drive should exhibit the following features: small steady-state error, robustness to variations in the system parameters, direct and fail-safe control algorithms, a fast transient response, small overshoot, a wide operating range, minimal maintenance, and low-cost applications [3].…”
