Study on Multi-Variable Control System for Vertical Rolling Mill
In this paper slab width control arithmetic is proposed in order to meet the stringent requirement on the plate dimensional tolerance. The system adopts an ANN inverse with fuzzy-PID as composite controller to account for the complicated process dynamics characterized by nonlinear, time-varying, uncertain and load couple properties. Firstly, the reversibility of the system is analyzed and the ANN inverse dynamic is constructed based on a feed forward and neural network structure with enlarged back propagation algorithm. Secondly, the system is changed into pseudo-linear system through connecting the controlled system and inverse dynamic model in series. Aim to pseudo-linear system a Fuzzy-PID controller is proposed. A series simulation was conducted to verify the performance of the proposed controller and showed the controller does well not only on decoupling but also the transient response and robustness under vary conditions.
