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 ...

Anti‐disturbance control for nonlinear system via adaptive disturbance observer

International Journal of Robust and Nonlinear Control, 2016
SummaryThis paper addresses the problems of disturbance estimation and anti‐disturbance control for nonlinear system with exogenous disturbance, which is generated from an unknown exogenous system. The state observer and the adaptive disturbance observer are designed, simultaneously.

Disturbance Observer‐Based Elegant Anti‐Disturbance Control for Stochastic Systems with Multiple Disturbances

Asian Journal of Control, 2017
AbstractDisturbance observer‐based elegant anti‐disturbance control (DOBEADC) scheme is proposed for a class of stochastic systems with nonlinear dynamics and multiple disturbances. The stochastic disturbance observer based on pole placement is constructed to estimate disturbance which is generated by an exogenous system.

Disturbance Observer-based Control

2011
In this chapter, it is revealed that a disturbance observer-based control scheme is very effective in controlling integral processes with dead time. The controller can be designed to reject ramp disturbances, step disturbances, and even arbitrary disturbances. Only two parameters are left to tune when the plant model is available.

Doppler observations of ionospheric disturbances

Contemporary Physics, 1970
Summary The Doppler shift in frequency of an ionospherically reflected radio wave can be used to study various ionospheric disturbances. In this article the experimental arrangement for measuring such a shift is described, and examples of frequency shifts associated with solar flares, geomagnetic variations and travelling disturbances are discussed.

Two-dimensional disturbance decoupled observers†

International Journal of Systems Science, 1987
A procedure is developed for the design of a minimal-order observer capable of estimating the states of a two-dimensional system in the presence of unknown inputs. This is done using singular-value decomposition. The assignment of eigenvalues to the observer is facilitated by choosing the observer structure.
