Simulation and Virtual control of BLDC Motor Drive Using Keil's and Proteus Software

The primary objective of this research work is to control the speed of BLDC motor. To achieve the speed control, the keil and proteus software are usedto control the BLDC motor microcontroller (AT89C51). The micro controller is used to set the speed ranges, which is done by changing the duty cycles time period in the program. As the frequency and speed are directly proportional to each other by controlling the frequency then the speed is controlled. The microcontroller frequency ranges can be set in the software. The MATLAB simulation tool is used to achieve the BLDC motor speed control and also the torque and speed waveforms will be obtained. The main advantage of this project is to reduce the cost and increase the reliability of this system, which can be more feasible to control the speed of the DC motor in less time.
