摘要
针对锅炉中主蒸汽温度控制系统中具有的非线性、参数时变性和系统大滞后等问题,以LabVIEW为平台,采用数据采集卡PCI-8360V实现上位机与控制平台的通信,设计并实现了锅炉主蒸汽温度控制系统。采用PID、模糊PID以及模糊积分等算法控制锅炉主蒸汽温度,同时通过数据采集卡获取这些数据,在可视化界面上以趋势图的方式实时显示。结果表明,控制目标温度和实际仿真数据的误差缩小到2~3℃,能够满足在50%~100%负荷之间,蒸汽温度的变化范围被控制在要求的-10^+5℃。
For nonlinear,parameter time-varying and big lag system of boiler main steam temperature control system,based on the Labview platform,data acquisition card PCI-8360-v,which is adopted to realize communication of upper machine and control platform,boiler main steam temperature control system was designed and implemented. Adopted PID control,fuzzy PID and fuzzy integral algorithm to control boiler main steam temperature,at the same time through access to the data acquisition card to accomplish the visual interface real-time display in the form of trend chart. Results show that the control error of the target temperature and the actual simulation data reduced to 2~ 3 ℃,can satisfy the between 50%-100% load,control the steam temperature range was-10 ~ ＋ 5 ℃ control requirements,with practical application value.
