Department of electronic and computer engineering hong kong university of science and technology hong kong china.

Closed loop control of brushless dc motor circuit diagram. For making this circuit the user will first make this circuit according to above block diagram and then tune pid controller according to their speed requirements. Abstract three phase miniature brushless dc bldc motors are very popular on small unmanned aerial vehicles uavs. Due to the shape and size limitation.

As the driver circuit can make use of any power switching element like mosfet igbt for its operation therefore it was decided to design a suitable drive circuit for the motor by making use of igbt. The block diagram below shows the operation flow of this circuit wherein the circuit connections are shown for each functionality. Closed loop speed control of miniature brushless dc motors.

Designing a drive circuit for a motor is a challenging task. Closed loop control for a brushless dc of bldc motor fed from llc lc using matlab simulink in systems electrical pm by six step inverter proposed system closed loop control for a brushless dc motor using pic microcontroller closed loop control of bldc motor closed loop control for bldc motor using pic 16f877a scientific diagram read more. In this closed loop control of bldc motor system the speed of dc motor is controlled through pid controller.

Overview of the project. This circuit comprises hardware components like 8051 microcontroller transformer mosfet keypad lcd voltage regulator capacitors diodes resistors opto isolators ir photo diode bldc.
