摘要
介绍了一个基于PWM 控制的温控系统设计和实现方法。着重讨论了系统的组成、控制原理及PID参数自整定的软件设计思想。实验结果表明,温控精度可达±0.2℃。
The design and implementation of a temperature control system based on PWM control are introduced. The system structure , control principle and the design concept of the software for selftuning of the PID parameters are discussed emphatically. The experiment result shows that the control accuracy reaches ±0.2℃.
