ABSTRACT
Motor speed control or round control is one of the important subjects in robotics and military industries.
The conventional control methods are robust control and classic control methods, however fuzzy–adaptive and adaptive methods are rarely used. Non-adaptive methods are not suitable in industries, because it is not possible to adapt with changes of parameters and if total dynamic system is not in access, parameters of controllers does not change with model parameters. Even in neural networks with sensitivity analysis, change of controller parameters is very complex.
In this project, we are using Pulse Width Modulation (PWM) for controlling the speed of DC motor. Here the person enters predefined commands from the key board to the serial port for controlling the speed. Depending on the command speed of the motor varies. Simulation is performed by 8051 microcontroller and L293D switches as driver. By using PWM method as drive method by switching circuit, total power loss can be reduced.
