Self-bounded controlled invariant subspaces in measurable signal decoupling with stability: minimal-order feedforward solution

Elena Zattoni (2005)

Kybernetika

Similarity:

The structural properties of self-bounded controlled invariant subspaces are fundamental to the synthesis of a dynamic feedforward compensator achieving insensitivity of the controlled output to a disturbance input accessible for measurement, on the assumption that the system is stable or pre-stabilized by an inner feedback. The control system herein devised has several important features: i) minimum order of the feedforward compensator; ii) minimum number of unassignable dynamics internal...

A feedforward compensation scheme for perfect decoupling of measurable input functions

Giovanni Marro, Lorenzo Ntogramatzidis (2005)

Kybernetika

Similarity:

In this paper the exact decoupling problem of signals that are accessible for measurement is investigated. Exploiting the tools and the procedures of the geometric approach, the structure of a feedforward compensator is derived that, cascaded to a linear dynamical system and taking the measurable signal as input, provides the control law that solves the decoupling problem and ensures the internal stability of the overall system.

On some geometric control properties of active suspensions systems

Domenico Prattichizzo, Paolo Mercorelli (2000)

Kybernetika

Similarity:

The geometric control properties of vehicles with active suspensions are analyzed. A special attention is devoted to the problem of disturbance decoupling. Active suspensions of advanced vehicles allow the active rejection of external disturbances exerted on the sprung mass of the vehicle and caused by road surface irregularity. We focus on the road irregularity disturbances with the purpose of isolating the chassis from vibrations transmitted through suspensions. The paper is aimed...
