Abstract: Today in industrial application, robotics, home appliances, etc. speed control of a motor is often required. In this paper We try to implement a BLDC motor speed control system. Basic idea of a speed control system is to maintain the speed of the motor at the desired value under several condition. Normally, The DC motor is a nonlinear device which have various changes in its speed because of change in load demand, disturbances. The tachometer is a very famous controller in industries so here we have implemented the Tachometer algorithm. Speed of motor is sensed by an optical switch which converted to feedback voltage. We use an IR sensor which detected the error signal on which The controller acts and generates appropriate control voltage. The PWM generator for control the speed of motor varies the duty cycle of the voltage supplied.
