A Progressive Rugged Appearance of Fuzzy Controller Fed Four-switch BLDC Drive

Brushless DC motors are promptly increased popularity because of its more efficiency & attain control characteristics with high accuracy speed. Need some digital controllers for sensing & regulating the disturbances by utilizing the several control logic units. The obstacles of formal PI controller for the speed control can be regulated by Fuzzy control units with affordable stability factor. This paper highlights the design of the four switch converter fed BLDC drive with Fuzzy controller supports the dynamically renew the parameters of formal PI controller. The intended control units have very moderate structures because of fuzzy rule in the rule based system is relevant to ease design using computer simulations. Simulation results are conferred satisfactorily in transient & steady states, low error values and with a high stability factor.
