Abstract: Due to Shortcomings of Low Accuracy and Response lag in various methods of the DC motor speed control, a comparison between different methods of DC motor speed control will be carried out. The Proportional Integral Differential (PID) controller design and selection of various Proportional, Integral and Differential control parameters according to various system responses is proposed in this paper. MATLABis a multi-paradigm numerical computing environment and proprietary programming language. It allows matrix manipulations, plotting of functions and data, implementation of algorithms. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems. We are using Simulink to implement the Proportional Integral Differential (PID) controller that can be used to control the speed of DC motor and bring it at the desired speed. Pulse width Modulation (PWM) is another technique which involves the use of the same simulation software. Hardware implementation requires the use of Infrared (IR) sensors and Arduino (open source platform for building Electronic project) for measuring the Rotations per minute (RPM) of the DC motor. Motor speed was measured using three techniques and a further comparison between these techniques is carried out according to the desired and control speed.The applications of our research could be in conveyors, turntables and others for which adjustable speed and constant or low-speed torque are required. It also works well in dynamic braking and reversing applications, which are common in many industrial machines.
