Performance Recovery and Stability Analysis of Disturbance Observer Under Unmodeled Dynamics [PDF]
SensorsFeedback system design is often achieved by neglecting the unmodeled dynamics, such as the actuator and sensor, to reduce design complexity. It is based on an assumption that the unmodeled dynamics are fast enough to be negligible.

Universal nonlinear disturbance observer for robotic manipulators
International Journal of Advanced Robotic Systems, 2023 Dynamic uncertainties and unknown disturbances will degrade the tracking performance of robots. When using a disturber observer-based controller, the key to effectively compensate for these uncertainties is to measure or estimate as accurately as ...

Bipartite Containment Disturbance Rejection Using Disturbance Observers
IEEE Access, 2022 This paper mainly addresses bipartite containment control of multi-agent systems (MASs) subject to exogenous disturbances. With dynamic gain technique independent of any global information, the disturbance observer method is applied to estimate disturbances generated by heterogeneous nonlinear exosystems.
