Disturbance Rejection Using SPR0 Substitutions

Disturbance Rejection Using SPR0 Substitutions

The disturbance rejection, defined as the problem of designing control laws that ensure, where possible, exogenous disturbances that do not affect the output of the perturbed system, has been resolved by means of algebraic and geometric techniques. This is a steady linear case by means of the static feedback state. Modifications of the Smith form through the SPR0 substitutions are presented whi...

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...

Adaptive disturbance rejection using ARMARKOV/Toeplitz models

An adaptive disturbance rejection algorithm is developed for the standard control problem. The multiple input–multiple output (MIMO) system and controller are represented as ARMARKOV/Toeplitz models, and the parameter matrix of the compensator is updated on-line by means of a gradient algorithm. The algorithm requires minimal knowledge of the plant, specifically, the numerator of the ARMARKOV m...

Nonlinear Robust Disturbance Rejection

This thesis studies the problem of robust disturbance rejection for nonlinear systems based on three different methods: H∞ control, singular perturbation theory and multiple model adaptive control. Firstly, the disturbance suppression problem for nonlinear systems based on H∞ control is examined. We review the so-called nonstandard mixed sensitivity problem, which introduces an integrator into ...
