摘要

提出了一种基于滑模观测器(SMO)的线性不确定系统鲁棒同步执行器和传感器故障重建方法。与现有工作相比，该观测器包含两个不连续项，解决了同时故障问题。该思想是在系统输出上引入适当的滤波器，将传感器故障转换为虚拟执行器故障，从而可以应用所提出的SMO。

Robust and simultaneous reconstruction of actuator and sensor faults via sliding mode observer

This paper proposes a method for robust and simultaneous actuator and sensor faults reconstruction of linear uncertain system based on sliding mode observer (SMO). In comparison with existing work, the observer contains two discontinuous terms to solve the problem of simultaneous faults. The idea is to introduce an appropriate filter on the systems output to transform the sensor faults in the fictitious actuator faults and hence the proposed SMO can be applied.
