Asymptotic disturbance rejection for hammerstein positive real systems

Asymptotic disturbance rejection for Hammerstein positive real systems

In this paper, we present control algorithms for stabilization and asymptotic disturbance rejection for Hammerstein systems with positive real linear dynamics. To do this, we extend the nonlinear controller modification technique of Bernstein and Haddad to include matched plant disturbances. The controller is based on a novel Lyapunov function that estimates the disturbance bound. These estimat...

DISTURBANCE REJECTION IN NONLINEAR SYSTEMS USING NEURO-FUZZY MODEL

The problem of disturbance rejection in the control of nonlinear systems with additive disturbance generated by some unforced nonlinear systems, was formulated and solved by {itshape Mukhopadhyay} and {itshape Narendra}, they applied the idea of increasing the order of the system, using neural networks the model of multilayer perceptron on several systems of varying complexity, so the objective...

Disturbance Rejection for Nonlinear Systems

Tracking or rejection of unknown exogenous signals with known generating dynamics is of major concern in feedback control design. Linear feedback control based on the internal model principle achieves asymptotic performance for linear systems with linear exogenous signal dynamics. This paper presents a control design based on the internal model principle to track or reject nonlinear exogenous s...

Disturbance Rejection Control in Coordinated Systems

Abstract: Coordinated system control with realistic disturbance is studied. We employ coordinated vehicles as an working problem. Vehicles attempt to keep a specified formation while avoiding collision in the presence of disturbance such as a wind gust. State estimators are used to estimate the self-states and the states of interacting vehicles via communication channels. Estimation performance...
