Abstract

In order to address the problem that the main drive system of rolling mill is easily affected by the impact of biting steel, and considering the nonlinear friction damping and the external perturbations of the main drive system of rolling mill during the rolling process, a fault model of the main drive system of rolling mill is established, and a fault diagnosis and fault tolerance control method of the main drive system of rolling mill based on the nonlinear sliding-mode observer is proposed. In order to suppress the influence of external perturbations on fault diagnosis, a nonlinear sliding-mode observer is constructed for fault diagnosis and fault reconfiguration of the system, and the robustness of the observer to fault reconfiguration is improved by using the sliding-mode control rate [Formula: see text], and the stability of the designed nonlinear sliding-mode observer is proved using Lyapunov’s stability theorem. In order to ensure that the system can operate normally even after a fault occurs, a reference model is designed, and a new controller is redesigned for fault-tolerant control of the system by adding a fault compensation term to the original control scheme using fault estimation information. Through the simulation study of the main drive system of stand F4 of 2030 mm cold rolling mill, it is verified that the observer can accurately track the system state with an angular velocity error of 2.45% and detect and estimate the main drive system failure of rolling mill with an estimation error of no more than 0.04% after a fault occurs; the fault-tolerant control of the main drive system of rolling mill is carried out by using the fault information to restore the system to its normal state, and the angular velocity error is 1.89%.

基于滑模观测器的轧机主传动系统故障诊断与容错控制
为了解决轧机主传动系统容易受到咬钢冲击的问题,并考虑轧制过程中轧机主传动的非线性摩擦阻尼和外部扰动,建立了轧机主传动故障模型,提出了一种基于非线性滑模观测器的轧机主传动系统故障诊断与容错控制方法。为了抑制外部扰动对故障诊断的影响,构造了一个非线性滑模观测器用于系统的故障诊断和故障重构,并利用滑模控制率提高了观测器对故障重构的鲁棒性[公式:见正文],并利用李雅普诺夫稳定性定理证明了所设计的非线性滑模观测器的稳定性。为了确保系统即使在故障发生后也能正常运行,设计了一个参考模型,并通过使用故障估计信息在原始控制方案中添加故障补偿项,重新设计了一种新的控制器,用于系统的容错控制。通过对2030年F4机位主传动系统的仿真研究 mm冷轧机,验证了观测器能够准确跟踪角速度误差为2.45%的系统状态,并在故障发生后以不超过0.04%的估计误差检测和估计轧机主传动系统故障;利用故障信息对轧机主传动系统进行容错控制,使系统恢复到正常状态,角速度误差为1.89%。
