摘要
温度控制是控制系统中最为常见的控制类型之一,而在传统的电阻炉控制系统中,温度控制起着至关重要的作用,但因其纯滞后、非线性等诸多因素,导致了调节时间长、控制精度低,成为电阻炉工作的干扰因素,不仅影响其工作效率,也给工业生产带来了极大不便。单片机的诞生改变了设计理念,电路设计简单、精度高等优势使得单片机在控制系统中,尤其是温度控制中得到了长足发展。文中采用单片机为温度控制器,应用数字PID算法对其进行调试。并就温度检测,温度控制,功率放大等进行了设计,控制系统的精度达到了工业生产的要求。
Temperature control is one of the most common type of control in the control system, and in the traditional resistance furnace control system, temperature control plays a vital role, but because of its pure time-delay, non-linear, and many other factors, led to the adjustment time is long, low control accuracy, interference factors become the resistance furnace, not only affect their work efficiency, also has brought great inconvenience to industrial production. MCU birth changed the design concept of simple circuit design, high precision makes single chip microcomputer in the control system, especially in the temperature control has been rapid development. This article namely by single chip microcomputer temperature controller, digital PID algorithm carries on the debugging. And temperature tests, temperature control, power amplifier and so on have carried on the design, the precision of the control system has reached the requirement of industrial production.
