摘要
为保证燃气锅炉安全稳定的运行,并针对传统温度控制算法存在的选取问题,提出一种改进型PID温度控制方法,并完成温控系统的设计。首先讨论燃气锅炉温度监控中的系统工作原理及硬件配置,分析通用PID温度控制方法存在的问题并进行优化和完善,通过升级PID控制算法提高温度的采集精度并完成梯形图的编写。最后,使用该方法完成新疆某锅炉控制系统的设计,应用结果表明,该方法在温度的控制范围、控制精度和响应速度上均更优,具有更广的应用前景。
In order to ensure the safe and stable operation of gas fired boiler,and aiming at the selection problem of traditional temperature control algorithm,an improved PID temperature control method is put forward,and the design of temperature control system is completed. First of all,the working principle and hardware configuration of the gas boiler temperature monitoring system is discussed. The existing problems of the general PID temperature control method are analyzed and optimized and improved. By upgrading the PID control algorithm,we can improve the collection accuracy of temperature and complete the compilation of ladder diagram. Finally,the design of a boiler control system in Xinjiang is completed by using this method. The application results show that this method is better in temperature control range,control accuracy and response speed,and has wider application prospects.
