Abstract

Hyperthermia is a healing method by increasing the temperature of the object above the normal physiology temperature, for the human temperature is 42⁰C until 45⁰C. Cancercous patient can be cured by hyperthermia's therapy. Temperature on hyperthermia’s range enough to kill tumour cells without destroying the healthy body tissues. A control system such as PID control is required to keep temperature stability on the hyperthermia’s range. This final project purpose to make PID control application in a model of hyperthermia system based on a noncontact temperature sensor, thermopile MLX90247. System will heat the cowhide tissues as sample tissues for 20 minutes therapeutic time. Temperature of the sample tissue can be measured by a noncontact temperature sensor, thermopile MLX90247 as a feedback on PID control systems to control the therapeutic temperature. The control output of PID control will give AC voltage control circuit firing that activate a light bulb as a heat actuator. The PID control system embedded on ATmega32 microcontroller that can operated by a keypad module and monitored by LCD or Personal Computer (PC). From the experiment result, we can get a conclusion that the PID control systems can applied properly in a model of hyperthermia’s system based on a non contact temperature sensor, thermopile MLX90247 by used Zieger Nichols tuning method. The results on tuning of PID control parameters are Kp = 66, Ki = 2, and Kd = 25. System reached the references on therapeutic temperature ranges at 42°C until 45°C and stable for 20 minutes therapeutic times. Key words : hyperthermia, PID control, ATmega32 microcontroller, noncontact temperature sensor thermopile MLX90247
