Dynamic disturbance decoupling for nonlinear systems [PDF]

SIAM Journal on Control and Optimization, 1992
In analogy with the dynamic input-output decoupling problem the dynamic disturbance decoupling problem for nonlinear systems is introduced. A local solution of this problem is obtained in the case that the system under consideration is invertible.

Nonlinear dynamic disturbance decoupling [PDF]

29th IEEE Conference on Decision and Control, 1990
The authors introduce the dynamic disturbance decoupling problem for nonlinear systems. A local solution of the problem is given. A compensator solving the problem can be obtained by means of S.N.

Disturbance-observer-based U-control (DOBUC) for nonlinear dynamic systems

, 2021
U-model, which is a control-oriented model set with the property of generally facilitate nonlinearity dynamic inversion/cancellation, has been introduced to the Disturbance Observer-Based control (DOBC) methods to improve the performance of the nonlinear

The time-dependent deformation and damage constitutive model of rock based on dynamic disturbance tests

Open Geosciences, 2023
In the deep rock excavation process, the rock will produce deformation and damage under multiple dynamic disturbances, while there is also unrecoverable time-dependent deformation.

Effect of Different Tunnel Distribution on Dynamic Behavior and Damage Characteristics of Non-Adjacent Tunnel Triggered by Blasting Disturbance

Mathematics, 2022
When a blasting is executed near two tunnels, the blasting wave will trigger a dynamic response and damage to the tunnels. Depending on the tunnel distribution, the path of the blasting wave to the remote non-adjacent tunnels will change. The aim of this
