Abstract
This paper describes the Fuzzy control of circular cooling water in a twin-roll strip cast, joins a feed-forward compensation to solve the time lag in conveying water. Because of the large time lag, multivariable system and hard modeling, this paper presents a Fuzzy controller for them. Based on the synthesis reasoning rules and Fuzzy logic, the Fuzzy model of circular cooling water is established. Then the simulation results show that the strip can effectively keep a constant temperature. And it has a good tracking performance, robust, strong anti-interference ability, and the cooling water can in time exchange heat with the liquid metal to get high quality strip.
