✦ Synopsis

The synthesis methodology developed by Kimura(1985) based on the design theory of output regulators essentially due to Wonham(1974) has been applied successfully to the flatness control system for a 6-high cold rolling mill. The system has the following remarkable features. ill The structure of the controller is simple. This makes it easy to tune the control system. {2) The controller copes well with the detection time delay, and thus high performance is obtained even at a low rolling speed. {3! The flatness error caused by the rolling force variation in mill acceleration and deceleration time would be kept to a minimum by the function to adjust roll bending force using the signal of rolling force.
