Adaptive Observer Based Fault Tolerant Control for Sensor and Actuator Faults in Wind Turbines [PDF]
Sensors, 2021 The installed wind energy generation capacity has been increasing dramatically all over the world. However, most wind turbines are installed in hostile environments, where regular operation needs to be ensured by effective fault tolerant control methods.

An Adaptive Control Strategy for DC/DC Converters Using Command-Filtered Backstepping and Disturbance Rejection [PDF]
MicromachinesEnsuring the stability and accuracy of the output voltage in DC/DC buck converters (DBCs) is critical for reliable operation. This paper investigates an observer-based adaptive command-filtered controller designed for DBC systems subject to lumped ...

Bearing Fault Identification Using Machine Learning and Adaptive Cascade Fault Observer
Applied Sciences, 2020 In this work, a hybrid procedure for bearing fault identification using a machine learning and adaptive cascade observer is explained. To design an adaptive cascade observer, the normal signal approximation is the first step.

Adaptive observers as nonlinear internal models [PDF]
Systems & Control Letters, 2006 This paper shows how the theory of nonlinear adaptive observers can be effectively used in the design of internal models for nonlinear output regulation. The theory substantially enhances the existing results in the context of {\em adaptive} output regulation, by allowing for not necessarily stable zero dynamics of the controlled plant and by weakening
