Disturbance decoupled functional observers

IEEE Transactions on Automatic Control, 1999
Summary: If a state observer does not exist, it is possible to design a functional observer. Principally, this is also true for systems with unknown inputs (termed as disturbances). Necessary and sufficient conditions for the existence of disturbance decoupled functional observers for linear time-invariant systems are provided.

Disturbance observers for constant disturbances

2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2019
The parameterization of linear disturbance observers for constant disturbances has been studied in this paper. By using the states and inputs of the system as variables, the parameterization under constant disturbances was obtained in frequency domain, the validity of the disturbance observer was proofed by simulation.

Disturbance observers for general exogenous disturbances

2019 IEEE International Conference on Mechatronics and Automation (ICMA), 2019
We examine a parameterization of linear disturbance observers for general exogenous disturbances. Using the states and inputs of the system as variables, we got an parameterization of linear disturbance observers for general exogenous disturbances in frequency domain formulation.

Novel robust disturbance observer

ISA Transactions, 2020
In this paper, a predictive disturbance observer (DOB) design is presented. The proposed DOB does not require a direct model of the process without the transport delay for prediction purposes. The primary advantage of the proposed DOB design is its simplicity due to usage of the prediction block (PB), which approximates the ideal anticipation object ...

Synthesized Disturbance Observer for Vehicle Lateral Disturbance Rejection

2018 Annual American Control Conference (ACC), 2018
Fast disturbance detection and compensation play an important role in vehicle steering control system. Disturbance observer (DOB) is an effective technique to compensate for the disturbance. However, the design procedure of the DOB requires a stable inverse of the plant and an additional $Q$ filter to guarantee the stability and the robustness to ...

Improvement of disturbance suppression based on disturbance observer

9th IEEE International Workshop on Advanced Motion Control, 2006., 2006
This research focuses on improvement of disturbance suppression even under existence of observation noise. Disturbance observer is an effective tool to estimate and compensate disturbance. There is a problem, however, that it cannot accomplish desired disturbance suppression when a large observation noise exists.

Fault diagnosis with disturbance rejection performance based on disturbance observer

Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009
In this paper, a new fault diagnosis approach presented for a class of non-linear systems with external urbances. The unknown disturbances are supposed to be rated by an exogenous system, where some classical assumptions on disturbances can be removed.

A survey of state and disturbance observers for practitioners

2006 American Control Conference, 2006
This paper gives a unified and historical review of observer design for the benefit of practitioners. It is unified in the sense that all observers are examined in terms of: 1) the assumed dynamic structure of the plant; 2) the required information, including the input signals and modeling information of the plant; and 3) the implementation equation of
