Design a Temperature Control System Using Halogen Lamp
In this paper, a temperature control system based on Halogen lamp is designed for education and training purpose, which is low cost, energy saving and less time consuming for student’s experimental task. The designed system consists of a box made of plastic and aluminum, a 300 W Halogen lamp, a temperature sensor, an Arduino Uno R3 based microprocessor, a triac BT137-600E by NXP Semiconductors and 220 V–50 Hz power supply. First, a transfer function from power to temperature is obtained through system identification based on a unit step response. Then, a PID controller is designed for the temperature. Finally, the temperature control system is verified through experimental tests. The results show that the temperature converges to the set-point with short settling time and small overshoot. The average time period for doing system identification and real-time control is quite small for student analyzing and performing experimental tasks. Moreover, since the cost of the designed system is cheap, it is possible to provide a system to each student for experiments. In addition, it can be also used as a testbed for verifying new control algorithms.
