Abstract:

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.
