An expert controller for the laminar cooling process of hot rolled slab

A fuzzy logic-based, multi-input/multi-output expert controller has been designed for laminar water curtain controlled cooling system at the Anshan Steel Corporation. This controller can automatically find the specified working points under boundary conditions instead of obtaining them from a lot of experiments. On the basis of these working points, the linearized models can be used to determine the control variables. The simulation results show that the expert controller has an excellent performance and can be used in a practical environment.
