A Guide to Design Disturbance Observer [PDF]
The goal of this paper is to clarify the robustness and performance constraints in the design of control systems based on disturbance observer (DOB). Although the bandwidth constraints of a DOB have long been very well-known by experiences and observations, they have not been formulated and clearly reported yet.

Disturbance observer is an inner-loop output-feedback controller whose role is to reject external disturbances and to make the outer-loop baseline controller robust against plant's uncertainties. Therefore, the closed-loop system with the DOB approximates the nominal closed-loop by the baseline controller and the nominal plant model with no ...

Consensus Disturbance Rejection With Disturbance Observers [PDF]
This paper deals with consensus disturbance rejection of network-connected dynamic systems using disturbance observers. The control objective of consensus disturbance rejection is to achieve a common state trajectory for the network-connected subsystems that are under deterministic disturbances.

Composite control method of DC motor based on speed feedback
In view of problems of slow response speed and bad anti-disturbance ability existed in traditional control system of DC motor, the paper proposed a composite double-loop control method of DC motor based on disturbance observer and speed observer.

Disturbance Observer-Based Frequency Regulation for Shipboard Microgrid With Communication Delay
Load frequency control of power systems is inherently a disturbance rejection issue. This paper proposes a disturbance observer-based frequency regulation approach for a shipboard microgrid system with communication delay.
