摘要
本文介绍了采用半导体制冷片TEC1-12708作为温度控制系统的执行部件的温度控制系统,运用分段PID控制算法改变单片机输出的PWM脉冲来控制制冷片工作状态,使水温能够自动调整到设定值,且温度控制动态响应好、上升时间快、超调小、稳态精度高,具有很好的实时性。
This article describes a temperature control system which uses semiconductor chilling plate TEC 1-12708 as the implementation.The temperature control system uses the segment PID control algorithm and changes the microcontroller output PWM pulses to control the working status of the cooling piece.System sets the water temperature can be automatically adjusted,and the temperature control dynamic response,fast rise time,small overshoot,high steady precision,good real-time.
