摘要：

The nonlinear torsional vibration model of main drive system in cold rolling mill was established, with the consideration of variable stiffness and friction coefficient. The system dynamic characteristics have been discussed by the influence of those nonlinear parameters. By introducing the nonlinear gain and friction compensation, a robust controller with nonlinear gain and friction compensation term, is presented, and its convergence is demonstrated based on Lyapunov direct method. Simulation experiment with industrial data demonstrates the effectiveness and better tracking behavior of the proposed algorithm.
