Fuzzy Logic Control of Three Phase Induction Motor Using Rotor Resistance Control Method

Abstract

This work is based on an intelligent speed control system with the application of fuzzy logic on a three phase induction motor. Fuzzy logic was applied to traditional method of speed control of three phase induction motor such as Rotor Resistance Control where inputs such as rotor resistance, line voltage and two loads attached to the motor were varied. With the variations in the inputs, it was observed that appropriate variations in outputs such as speed, slip, torque, output power and efficiency were achieved. By using the Mamdani Fuzzy Model, an analysis of rule-based Fuzzy Logic Controller was applied in which the system can be taught to predict the output depending on the variations in the input variables.
