Fault-Tolerant Control Against Actuator Faults for Hydrofoil Attitude Control Systems via a Cascaded Extended State Observer

IEEE Transactions on Instrumentation and Measurement
Due to challenging underwater conditions, hydrofoils serving as actuators within the hydrofoil attitude control system (HACS) are prone to failures that can lead to system instability and the inability to complete the intended mission. Fault tolerance in

H∞Filter and Extended State Observer-Based Disturbance Rejection Control for Systems With Uncertainty and Noise

IEEE Transactions on Circuits and Systems Part 1: Regular Papers
The extended state observer (ESO) is widely used in disturbance rejection methods for its ability to achieve rapid convergence through high-gain design. However, this high-gain ESO often leads to significant noise amplification and increased sensitivity ...

Disturbance-Compression Extended State Observer With Noise Insensitivity: Application to Electro-Optical Tracking System

IEEE Transactions on Automation Science and Engineering
While augmenting the observer gain can diminish the estimation errors of the extended state observer (ESO), it inevitably leads to an amplification of the observing noise, thus creating the trade-off between high-gain observation and noise sensitivity ...
