PERFORMANCE EVALUATION OF FUZZY LOGIC CONTROL OF INDUCTION MOTOR
Journal Title: World Journal of Engineering Research and Technology - Year 2017, Vol 3, Issue 5
Abstract
Speed control of induction motors has been a challenge mostly during industrial processes. These motors are used to carry out different task at different speeds. A three phase induction motor is a constant speed motor; therefore, it is difficult to control its speed especially maintaining a constant speed with load variation. There is a tradeoff in efficiency and power factor when the speed of the motor is being controlled. Different methods of speed control have been proposed and used with their attended advantages and disadvantages. In this paper, Fuzzy logic is used to control the speed of an induction motor under load variation. The control architecture includes some defined fuzzy rules, which portray a nonchalant relationship between the two inputs; speed error (e) and change in error (Δe), and the output frequency or change in control (). The errors are evaluated according to the rules by the defined member functions. The system model is simulated in MATLAB/SIMULINK and the simulated results presented. The results obtained using a conventional PI controller and the designed Fuzzy Logic Controller has been studied and compared. The FLC presents better performance in terms of stability, precision and reliability when compared to the PI.
