Abstract
The new roll eccentricity control system which is an application of the synthesis methodology developed by Kimura based on the design theory of output regulations essentially due to Wonham has been developed and its effectiveness has been demonstrated by the application results to a real plant. The salient features of the new system are as follows.
(1) The roll balancing force regulator is applied effectively instead of the hydraulic roll position regulator.
(2) The controller obtained from the observer-based design method copes well with the actuator and detection time delay without complication of the controller.
(3) The use of the so-called gaugemeter equation for the roll eccentricity estimation leads to the feature that gain tuning with the rolled material variation is no need.
