Abstract:

In this paper, a water temperature control system in a Pirex tank is designed for education and training purpose. Students can also use this system to conduct experiments in the scientific research topics. Our first task is to build mathematical model based on physical laws. After that the transfer function parameters are identified experimentally based on the step input response. Water temperature control system required to reach to the temperature set-point in a certain range of time and to avoid overshooting and steady-state error. Therefore, the PID controller, MPC controller and SMC controller featuring a PID-type sliding surface are designed and compared. Finally, simulation results show that the control system works stably and the short settling time and small overshoot. The main advantage of SMC and MPC is its ability to reject disturbances and deal with system uncertainties better than PID while its drawback is the chattering effect which is again addressed in literature by different techniques. In addition, it can be also used as a tested for verifying new control algorithms.
