The Application of GPC Decoupling Control in Tubular Furnace
Furnace as a control system whose conditions complex, parameter changing , great runing inertia ,control action delay . Of which there are many uncertainties ,such as air, fuel gas pressure and the frequent fluctuations of the fuel’s calorific value . The impact of mutual interference and coupling between the variables to the furnace can not be ignored , though it’s not dominant .The systerm based on control model use an advanced generalized predictive control (GPC) algorithm control mode .It can improve the control accuracy of regulator action when the furnace is at the condition of stability .The experiment results show that ducoupling GPC algorithm has a good convergence effect .
