Fault-Reconstruction-Based Cascaded Sliding Mode Observers for Descriptor Linear Systems
This paper develops a cascaded sliding mode observer method to reconstruct actuator faults for a class of descriptor linear systems. Based on a new canonical form, a novel design method is presented to discuss the existence conditions of the sliding mode observer. Furthermore, the proposed method is extended to general descriptor linear systems with actuator faults. Finally, the effectiveness o...
متن کاملRobust Fault Reconstruction for LPV Systems Using Sliding Mode Observers
This paper presents a robust FDI scheme using a sliding mode observer based on an LPV system, with fault reconstruction capability. Both actuator and sensor fault reconstruction schemes are considered which possess robustness against a certain class of uncertainty and corrupted measurements. For actuator fault reconstruction, the input distribution matrix (associated with the actuators being mo...
متن کاملSliding Mode Observer-Based Fault Reconstruction for Uncertain Linear Systems
Problem statement: Fault reconstruction scheme is different from the majority of Fault Detection and Isolation (FDI) methods described in the literature in the sense that it not only detects and isolates the fault, but provides an estimate of the fault. This approach is very useful for incipient faults and slow drifts, which are very difficult to detect. Also, this approach is very useful for F...
متن کاملSensor Fault Detection for a class of Uncertain Nonlinear Systems Using Sliding Mode Observers
This paper deals with the issues of sensor fault detection for a class of Lipschitz uncertain nonlinear system. By definition coordinate transformation matrix for system states and output system, at first the original system divided into two subsystems. the first subsystem includes uncertainties but without any sensor faults and the second subsystem has sensor faults but is free of uncertaintie...
متن کاملSliding Mode Observers for Robust Fault Detection and Reconstruction
This paper describes a method for designing sliding mode observers for detection and reconstruction of faults, that is robust against system uncertainty. The method uses H∞ concepts to design the observer, minimising the effect of the uncertainty on the reconstruction of the faults. A VTOL aircraft example taken from the fault detection literature is used to demonstrate the method and its effec...
