Design and Simulation of Mamdani-flc Based Drive System

A novel design of an FL controller to control the IM speed using SVPWM technique for voltage source inverter is presented in this chapter. The IM drive's performance largely depends on the usage of electronics coupled with excellent control strategies in the hardware implementation. In this context, the FLC has been found to yield impressive results in drives as the control technology. The conventional control method requires system mathematical model and the system behavior is not satisfactory due to parametric variations, but FLC based system is designed without using mathematical model. Further, a rule-based FLC is designed using the SVPWM concept and applied to control the speed of an IM, as proposed in this chapter. It has very good accuracy, low cost and simplicity. Flexibility is present while selecting the switching modes of the inverter. In this context, a Matlab / Simulink model is developed for simulation and further validated for speed control through simulations. Using SVPWM techniques, the duty cycle of the inverter can be calculated. Thus, this method definitely improves the performance of IM compared to the other methods. The proposed method's
