Nonlinear Looper-tension Control for Hot Strip Finishing Mill Using Feedback Linearization
Abstract: This paper studies on the design of a nonlinear controller for the looper-tension system in hot strip finishing mills using a static state feedback linearization and an ILQ(Inverse Linear Quadratic) Optimal Control. Nonlinear dynamic equations of the looper-tension system are analytically linearized by a static feedback linearization algorithm with a compensator. A nonlinear controlle...

متن کاملLooper-Tension Control for Hot Strip Finishing Mills Based On the Combination of H∞ and ISMC Approaches
The development of an innovative controller for looper and tension control in hot strip finishing mills is traced based on the combination of H∞ and ISMC (integral sliding mode control) approaches. First, an H∞ controller is designed to robustly attenuate the unmatched disturbances in the angle and tension loops. Then, ISMC is used to overcome the matched disturbances in the actuators which gua...
متن کاملA MPC for Start-up Phase Tension and Looper Control in Hot Strip Finishing Mills Using Continuation Approach
TThis paper gives a design method for a model predictive control (MPC) approach based on a unified performance index throughout the start-up phase tension and looper control which consists of the non-contact and contact modes in order to suppress the deviation of the strip tension while the looper contacts with the strip as quickly as possible. We will formulate the control problem by using a M...
متن کاملTension Control with ARHC Scheme for Hot Strip Finishing Mills
This paper presents a design procedure of the ARHC(Adaptive Receding Horizon Control) of the looper-tension controller in hot strip finishing mill. The controller is applied to satisfy the constraints of the control input and attenuate the disturbance of the actuator. The system matrices of the looper model are periodically updated during online simulation. Moreover the closed loop stability of...
