Observer-based fault-tolerant control against sensor failures for fuzzy systems with time delays

Observer Based Fault-tolerant Control for Fuzzy Systems with Sensor and Actuator Failures

This paper proposed an observer based fault-tolerant control approach for the fuzzy T-S systems with sensors and actuators faults. By establishing the actuator fault and sensor fault models, an observer based fuzzy output feedback fault tolerant controller is developed and new stabilization conditions of the fuzzy fault tolerant control systems are given, which are formulated in terms of linear...

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

Guaranteed Cost Fault-tolerant Control of Networked Control Systems with Short Output Delay and Short Control Delay Based on State Observer

Supposing that the sensor and controller nodes were time-driven and the actuator node was event-driven, the problem of integrity against sensor failures for the networked control systems with short output delay and short control delay was discussed based on observer. The state observer of the system according to the time-delay compensation strategy was designed. Then, considering possible senso...

Control of Interacting Level Process Under Sensor Failure Conditions using Coactive Adaptive Neuro-Fuzzy Observer

This paper presents the design of Coactive Adaptive Neuro-Fuzzy Observer based sensor fault detection and fault tolerant control under sensor failure conditions for a three-tank interacting level process. Fault detection is performed by estimating the states of the level process and comparing them with measured values. A fault is signaled when the difference between the estimated and measured v...

A Fuzzy Approach for Sensor Fault-Tolerant Control of wind energy conversion Systems

This paper presents the robust fuzzy fault tolerant control (FFTC) for nonlinear wind energy conversion systems (WECS) in the presence of bounded sensor faults and the state variable unavailable for measurement based on Takagi-Sugeno (TS) fuzzy model. Sufficient conditions are derived for robust stabilization in the sense of Lyapunov asymptotic stability and are formulated in the format of line...
