The Microcontroller based adjustable closed-loop DC motor speed controller systems has already become an important drive configuration for many applications across a wide range of power and speed. This is due to their simple control, high reliability, low cost and fast response and ability to work in all the four quadrants. Control System Design and Analysis technologies are widely suppress and very useful to be applied in real-time development. Some can be solved by hardware technology and by the advance use of software, control system are analyzed easily. This paper deals with the digital control of DC motor. The motor is controlled in all the four quadrants; in fact energy is conserved during the regenerative period. The digital controller dsPIC30F4011 is used, as it is very advantageous over other controllers, as it combines the calculation capability of Digital Signal Processor and controlling capability of PIC microcontroller, to achieve precise control. In this paper, control techniques of dsPIC30F4011 microcontroller and MOSFET are analyzed by mainly focusing with the Modeling and Simulation of DC Motor using MATLAB. The simulation model is developed using MATLAB/SIMULINK environment. The reason for choice of MATLAB/SIMULINK as development tool is, it is the most important and widely used simulation software. The prototype hardware set is tested in the power electronics laboratory for motor rating of 1HP. The setup is tested for open & closed loop control of motor.
