Heat exchanger plays vital role in chemical plants because they can withstand wide range of pressure and temperature. The heat exchanger transmit heat from hot liquid to cold liquid in order to avoid the loss of heat in chemical processes. Here we proposed different tuning strategies of PID controller for control the cold water temperature at desired set point. The best controller tuning method is found out from the transient response performance and the error criteria. The simulation is performed using MATLAB for different tuning strategies of the PID controller. The model result ensure that the Particle Swarm Optimization based PID provides efficient control action than conventional PID and Internal model control based PID controller.
Heat exchanger plays a important role in many unitsas they have the capability to hold different temperarure and pressure range. In this paper the linear quadratic controller and Dynamic matrix controller is implemented for heat exchanger system. The out let temperature of the tube is controlled by monitoring the inlet flow rate by using different controllers. The model of the system has been obtained from experimental data using system identification technique. The LQR and DMC is compared by analyze the servo performance in the system in terms of settling time, overshoot and rise time.
