| Load/pressure plant of turbine-generator unit is a complicated multivariable control plant. Its strong coupling and large inertia is all along a difficult problem in industrial controls. This paper introduces Neural Network into control system. It uses BP network constructing a new kind of dispersive decoupling network. Then based on it, an internal model control based on Neural Network is composed. Through emulation and robust analysis for the boiler plant of a coordinated control system, the paper illuminates the vast foreground of this method for controlling complicated industrial processes.
