基于双PID控制的温度控制系统的设计与实现
Design and Implementation of Temperature Control System Based on Double PID Control
摘要
Abstract
In order to enable the semiconductor laser to achieve a stable working state quickly,a high precision Thermoelectric Cooler(TEC)temperature-controlled circuit is proposed and experimentally demonstrated by using series double PID,a microcontroller of Freescale Semiconductor MC9S12XS128MAL is used in the controlled cir⁃cuit,and a negative temperature coefficient thermistor is used to collect temperature information ,the TEC chip is derived by the driving circuit with two BTN7971 chip to drive the TEC work,in the software programming,the sta⁃bility control of the temperature is realized by using the PID algorithm and the closed loop negative feedback struc⁃ture. In the experiment,when the temperature rises from 26.6℃to 40℃,the stabilized time is within 40 s,and the overshoot is about 0.1%,and when the temperature drops from 26℃to 10℃,the stabilized time is about 50 s. Com⁃pared with the conventional PID control system,the system has better dynamic performance.关键词
