Abstract: The day to day requirement of technical parameters for industry being analysed by many researchers, but here we considered the analysis of temperature. Then the temperature process model is identified as first order plus dead time model (FOPDT). For the obtained model the Proportional-Integral-Derivative (PID) controllers are tuned using traditional technique, Zeigler Nichols (ZN) method, then particle swarm optimization technique (PSO). Tunned PID controllers values are implemented in closed loop environment using Matlab Simulink platform. A comparative analysis is proposed and the efficiency of the controller is evaluated based on time domain specification and error criterion analysis being achieved. For minimizing the error and enhancing the process reaction time with controller reliable parameters is proposed for the real time industrial application.


Keywords: PID controller, Z-N method, PSO, Temperature process, First order system.
