Data-driven Discrete Terminal Sliding Mode Method for Carbon Fiber Diagonal Loom Tension Networked Control

Abstract

A data-driven discrete-time terminal sliding mode control method for carbon fiber diagonal loom tension networked control is proposed in this paper. Firstly, the influence of introducing network factors is fully considered, and a tension model containing network factors is finally established. Then, considering the nonlinear characteristics, a data-driven modeling method is introduced, and the single-step delay method is used to estimate the unknown total disturbance to improve the robustness of the system, a discrete terminal sliding mode surface is designed to compensate the influences of time-delay and packet loss, and a discrete terminal sliding mode controller with prescribed performance constraints is designed to further accelerate the error convergence speed and improve the control accuracy. Finally, the effectiveness of the control method is proved according to the simulation results.
