Research on coke oven gas-collector pressure decoupling control

The gas-collector pressure control system of coke oven has the time-varied characteristic with strongly coupling, high non-linear, which is influenced by the process disturbances with high amplitudes. Based on the introduction about the coke oven gas collector coupling and its effect, all kinds of control method settling out the coupling of the gas collector pressure system are discussed in details, such as fuzzy controller, neural network controller, expert controller and hybrid intelligent controller. In the end, the existed problems and future research directions in the related field is concluded.
