温度控制系统广泛应用于工业控制领域。加热炉温度控制在许多领域中得到广泛的应用。加热炉温度是一个大惯性系统,一般采用PID调节进行控制,随着PLC功能的扩充,在许多PLC控制器中都扩充了PID控制功能,因此在逻辑控制与PID控制混合的应用场所中采用PLC控制是较为合理的。文章是利用西门子S7-300PLC控制加热炉温度的控制系统。
Temperature control system is widely used in industrial control. Furnace temperature control is widely used in many fields. Furnace temperature is a large inertial system, the general use of PID control to adjust, with the expansion of PLC function, in many PLC controllers have extended the PID control function, so the logic control and PID control hybrid applications in the use of PLC Control is more reasonable. Article is the use of Siemens S7-300PLC furnace temperature control system.
