Aiming at the influence of speed tracking performance caused by load disturbance, parameters perturbation and other uncertainties in the cold strip rolling mill, a speed tracking adaptive backstepping control strategy based on integral and time-varying sliding mode is proposed in this paper. Backstepping technology is used to design the speed loop controller and current loop controller to make the...
Hydraulic screwdown system of cold strip mill is nonlinear, time-variant system and it is disturbed by many factors, so the turning quality of controller influences the accuracy of Automatic Gauge Control (AGC). In this paper an optimum design method based on particle swarm optimization (PSO) algorithm is presented for PID controller parameters optimization of hydraulic servo screwdown system of one...
In view of the case that time-delay arises in the output measurements and the states are not all measurable in practical engineering control, the robust output feedback stabilization problem is investigated for a class of nonlinear time-delay systems in the presence of delayed output measurement. First, based on Lyapunov-Krasovskii functional stability theory, a sufficient condition is given under...
