【Abstract】 Dual-control method is applied to the controlling of the glass furnace temperature system,and decoupling control between oil pressure and flux is implemented.The inverse controller,which based on dynamic recursion neural networks,is used as the main controller,and is trained online by feedback error learning strategy.An improved Levenberg-Marquardt algorithm is proposed and applied to adjust the weights of the neural networks.A normal PI controller is used as the ancillary controller.Both the main and ancillary controller act on the testing object,they work jointly to obtain high control quality.Simulation results show the validity of this control strategy.更多还原
