Study on PIDNN Control of Circulating Fluidized Bed Boiler based on T-S Model

摘要

—Temperature and pressure are two main parameters of CFBB in the control system. Because of the CFBB possess the characteristics of time-varying, large lag and strong coupling, it is difficult to set up the arithmetical model and achieve better control effects. According to above difficulties, this paper adopts T-S fuzzy modeling method to description the input-output relationship for the control system based on collected data of system. On this basis, it adopts the PIDNN controller algorithm which has very strong adaptability and the whole system simulation is carried out by using MATLAB. The results of simulation experiment show that the designed model is effective and the control system achieves satisfied control effect.
