Abstract :
This paper presents a direct torque control technique for brushless DC motors with non-sinusoidal back electromotive force. Direct torque control has some benefits such as faster torque response and reduced torque ripple for driving the brushless DC motors. In order to solve the problems associated with conventional PI speed controller, a speed control based on fuzzy logic controller is proposed to reduce starting current, eliminate overshoot in the torque and speed responses, simplify designing and eliminating complex math formulas. To reduce rising time PD controller used with fuzzy logic control. The effectiveness of proposed system has been validated by simulation results.
