The Decoupling Control of Tandem Cold Rolling Tension and Gauge

Abstract

Tension and gauge control interact each other intensively in tandem cold rolling process, making control ineffective and unstable. In order to improve the thickness of the strip and tension control accuracy, control system of tandem cold rolling is equipped with the decoupling control of tension and gauge. Applying the method of Neural Network Simple Adaptive Control based on Genetic Algorithm, we design the Neural Network Simple Adaptive Control multi-variable decoupling control system of tension and gauge, The three layer neural network with genetic algorithm is used to decouple the tension and gauge system of cold rolling mill. The simulation result proves that the decoupling control of tension and gauge can be realized, furthermore, the dynamic and static characteristic of control system is better.
