Robust Linear Output Regulation Using Extended State Observer [PDF]
Mathematical Problems in Engineering, 2018 This paper presents a disturbance rejection-based solution to the problem of robust output regulation. The mismatch between the underlying plant and its nominal mathematical model is formulated by two disturbance classes. The first class is assumed to be generated by an autonomous linear system while for the second class no specific dynamical structure

Parameterization of a Novel Nonlinear Estimator for Uncertain SISO Systems with Noise Scenario
Mathematics, 2022 Dynamic observers are commonly used in feedback loops to estimate the system’s states from available control inputs and measured outputs. The presence of measurement noise degrades the performance of the observer and consequently degrades the performance

Machines, 2023 This paper presents a novel extended state observer (ESO) approach for a class of plants with nonlinear dynamics. The proposed observer estimates both the state variables and the total disturbance, which includes both exogenous and endogenous disturbance.

A Separation Principle on Lie Groups [PDF]
, 2010 For linear time-invariant systems, a separation principle holds: stable observer and stable state feedback can be designed for the time-invariant system, and the combined observer and feedback will be stable.
