Active Compensation Fault-Tolerant Control for Uncertain Systems with Both Actuator and Sensor Faults [PDF]
SensorsThis paper develops a novel fault reconstruction (FR) method and an FR-based fault-tolerant control (FTC) scheme for systems suffering from both sensor and actuator faults based on the combination of a Luenberger-like reduced-order observer and an ...

Simplified Interval Observer Scheme: A New Approach for Fault Diagnosis in Instruments [PDF]
Sensors, 2011 There are different schemes based on observers to detect and isolate faults in dynamic processes. In the case of fault diagnosis in instruments (FDI) there are different diagnosis schemes based on the number of observers: the Simplified Observer Scheme ...

Interval observers for discrete-time systems [PDF]
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012 Summary: Interval observers are constructed for discrete-time systems. First, time-invariant interval observers are proposed for a family of nonlinear systems. Second, it is shown that, for any time-invariant exponentially stable discrete-time linear system with additive disturbances, time-varying exponentially stable discrete-time interval observers ...

Fractional-Order Interval Observer for Multiagent Nonlinear Systems
Fractal and Fractional, 2022 A framework of distributed interval observers is introduced for fractional-order multiagent systems in the presence of nonlinearity. First, a frame was designed to construct the upper and lower bounds of the system state. By using monotone system theory,

A survey on interval observer design using positive system approach
Franklin Open, 2023 Interval observers provide an interval state estimate for system states that cannot be measured directly at any moment. The core idea for the interval observer design is to provide the cooperativity of the estimated error dynamic system through a proper ...

Stabilization for switched linear systems: Hybrid observer‐based method
IET Control Theory & Applications, 2021 This paper investigates interval observer‐based controller design for switched linear systems involving additional disturbance and measurement noise, whose modes need not to be cooperative.
