Abstract: The reasonable bending force preset has a deep impact on strip flatness and yield. In this article, the optimal objective function bending force is established. The impact of roll thermal expansion and roll wear on roll gap crown is analyzed. The optimal bending force model is established. Rosenbrock algorithm is adopted by the model to solve the optimal bending force .The strip flatness control deviation is effectively decreased by the calculated bending force. The yield is increased markedly. The model has been applied into a 1450mm five-stand cold rolling process control system successfully and a good effect is achieved.

Abstract: For a class of multi-input multi-output (MIMO) nonlinear system with time-delay, a problem of adaptive output tracking is investigated. Through applying the back-stepping recursive method, an adaptive output tracking controller is designed to achieve robust control. According to Lyapunov stability theory, Barbalat lemma, and Gronwall inequality, the designed state feedback controller not only guarantees the system states are uniformly bounded, but also ensures the system tracking error converges to a small neighborhood.

Abstract: To solve the problem that wheeled robot in the path tracking is prone to slip or roll over at a sharp curve, structure of the wheeled robot and its path tracking features are analyzed, and a new Fuzzy-Neural Network (FNN) based path tracking method of two-stage (route and speed) control is proposed. In the first stage, a FNN controller determines the robot’s turning radius by processing robot’s pose information. In the second stage, the secondary controller adjusts angular and linear velocities by taking advantage of the turning radius and condition of the path ahead. The experiments show that the controlled robot can track the planned path accurately and robustly when it runs at high speed; the process of path tracking is stable and no slipping and rolling occur.
