| Abstract: | In order to control the temperature accurately, a method to realize the function of pulse width modulation （PWM） by means of the AT89S52 timer and digital PID control is proposed according to the available temperature controlling system and temperature sensing principle of DS18B20. The digital PID control algorithm for the thermostatic control is discussed. A control system of MCU was realized ultimately by means of C51 program on the basis of the temperature sensing principle of the temperature sensor DS18B20. The application results show that this system has the advantages of good control effect, high accuracy and small overshoot, and all the performance indexes can meet the requirement. |
