摘要:
功率设备在运行的时候对温度有着较高的要求，需要配合冷却系统保持预定工作温度才能正常运行，但冷却系统的冷却液温度控制的大惯性、多变量，以及时变参数等特性会导致控制速度慢、精度低等问题。该文提出一种基于PLC的模糊PID冷却液温度控制系统，介绍了系统硬件以及软件的设计。该设计应用PLC实现了对温度调节过程的实时控制和数据采集，系统中的模糊控制和PID调节均通过PLC来实现。实验结果表明，该系统运行稳定，调节速度快，误差小，并具有实时显示、数据保存等功能，可以使用该系统对需要降温的功率设备进行冷却及温度控制。
Abstract:
The power equipment has high temperature requirements during operation, and it needs to cooperate with the cooling system to maintain the predetermined working temperature to operate normally. However, the large inertia, multivariable, and time-varying parameters of the cooling system temperature control of the cooling system may cause control. Slow speed, low precision and other issues. In this paper, a fuzzy PID temperature control system based on PLC is proposed. The hardware and software design of the system is introduced. The design uses PLC to realize the real-time control and data acquisition of the temperature adjustment process. The fuzzy control and PID adjustment in the system. All of them are realized by PLC. The experimental results show that the system is stable in operation, fast in adjustment, small in error, and has functions such as real-time display and data saving. The system can be used for cooling and temperature control of power devices that need to be cooled.
