Demonstration of Control System by using Microcontroller

Temperature controllers based on proportional-integration-differentiation (PID) control strategy are widely used in many industries. The main reason for the versatility of (P-I-D) is relatively simple structure, which can easily understand and implemented in practice. This paper describes in detail the design of a PI, PD and PID controllers for temperature control of a heating coil the main aim is to show the temperature controlling in real time environment with the help of MATLAB. This method offers advantage such as high-speed computation, real-time processing, low power consumption and also results in cost reduction
