Implementation and analysis of PID Control for Radiator temperature in a mini automated plant

Abstract

For stable operation of any process the constants of the PID controller (Kp, Ki, Kd) needs to be adjusted. Automatic tuning adjusts the constants for stable operation. However when automatic tuning is not available then manual methods based on the Nichol’s rules are used to determine the optimum PID constants values for smooth loop operation and to control process variables. In this paper, manual tuning PID controller is incorporated and then controller is implemented to stabilize the radiator temperature in a mini automated plant.
