Over the years, induction motors have been reliable choice in industry for electromechanical device. On account of its robust construction, low maintenance cost and wide range of load carrying capacities they found a wide range of applications. Typical industrial applications include generators, fan loads, and compressors. Motor starting on isolated or vulnerable grid systems is a highly unstable process which may cause harm to motor and load. The induction motor draws reactive lagging currents during steady-state operation, and is subjected to variable grid voltages that decrease motor working performance and life expectancy. To improve motor performance and overall system efficiency, soft start and speed control methods are available which are often referred as electrical drives and particularly for the system under consideration, as induction motor drives. The conventional induction motor drives are made intelligent with modern PWM and closed loop control techniques. This paper explores fuzzy logic based speed control of three phase induction motor. MATLAB simulation and results are explained.
