Conceptual design of heating power control system for passive cooling system simulation facility using PID control-based LabView

Abstract The on-off control system applied for heating power control in passive cooling system simulation (FASSIP) facilities resulted in a high overshoot of the experimental data. Developing a heating power control system into a PID control system is expected to reduce overshoot without increasing the rise time of the experiment. LabView-based PID control system for heating power control can be done by specifying the desired setpoint and then keeping the actual temperature of the water stable with minimal error. The temperature difference between the setpoint and the actual temperature becomes the input data of the PID system to calculate and analyze the amount of heating power so that the water temperature in the heating tank remains at the setpoint value. The output of the PID control system can be in the form of a duty cycle switch controller or it can also be an analog signal fed to the power controller (Silicon Controlled Rectifier/SCR) so that the power provided to the heater is in accordance with the calculation of the PID system.
