-In the industrial production process for a pure delay, time-varying, strong coupling phenomenon of multiple-input multiple-output is proposed based on fuzzy neural network PID control decoupling and combining the system decoupling control method. This method does not require the establishment of multi-variable mathematical model of the object accurately, through the strong coupling large delay and large inertia of the circulating fluidized bed boiler bed temperature- the main steam pressure simulation objects, and the results show that decoupling control works well, with good static, dynamic and robust.
