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 sys-tem of AMT vehicle is feasible and effective.
