摘　　要：针对具有非线性特性的自动离合器系统,设计了一种鲁棒故障检测滤波器,以检测自动离合器系统的突变和缓变故障。采用线性矩阵不等式的方法,给出存在故障检测滤波器的充分条件,使误差系统渐近稳定并且满足鲁棒H∞性能指标,并提出了基于残差均方值的故障检测策略。仿真结果经试验验证表明:所提出的故障检测方法用于AMT汽车自动离合器系统故障检测是可行而有效的。In the view of the nonlinear characteristics of automatic clutch system,a robust fault detection filter is designed to detect the abrupt and incipient faults of automatic clutch system. A sufficient condition is also derived in terms of linear matrix inequality,making the system asymptotically stable and meets the requirements of robust H∞performance. In addition,a scheme of fault detection based on residual mean squares is proposed. The simulation results are verified by tests,showing that the fault detection scheme proposed for the automatic clutch system of AMT vehicle is feasible and effective.
