Original Kurzfassung:
This paper is concerned with the controller design for the position control of the hydraulic adjustment system within the AGC (automatic gauge control) loop in hot and cold rolling mills. Since the hydraulic adjustment is nonlinear in nature and the plant operators want the dynamic behavior of the plant to remain the same all over the operating range, a special nonlinear controller based on differential geometric methods is developed. The problem becomes more difficult because not all quantities are measurable and the measured quantities are corrupted by transducer and quantization noise. Furthermore, the control concept comprises a plug-in controller based on the projection theorem in a Hilbert space for the active compensation of roll eccentricity-induced periodic vibrations. These vibraions appear as periodic disturbances in the strip exit thickness and they may even define the limits of the achievable thickness tolerances.
