Disturbance decoupling for descriptor systems by behavioral feedback

Disturbance decoupling for descriptor systems by behavioral feedback

We study disturbance decoupling for linear descriptor systems. Compared to previous approaches, where state feedback is used, we use the concept of behavioral feedback which allows to study a larger class of systems. We derive geometric characterizations for solvability of the disturbance decoupling problem following the classical approach. Exploiting the freedom in the choice of the behavioral...

Disturbance Decoupling for Descriptor Systems by State Feedback

We study the disturbance decoupling problem for linear time invariant descriptor systems. We give necessary and suucient conditions for the existence of a solution to the disturbance decoupling problem with/without stability via a proportional and/or derivative feedback that also makes the resulting closed-loop system regular and/or of index at most one. All results are proved constructively ba...

Disturbance decoupling by measurement feedback for structured transfer matrix systems

A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract Structured transfer matrix systems are linear systems given by transfer matrices of which the innnite pole order of each nonzero entry is known, while the associated innnite gains are unknown and assumed mutually independent. In this paper necessary and suucient conditions are derived for the ge...

Disturbance decoupling by measurement feedback

The paper addresses the disturbance decoupling problem for MIMO discretetime nonlinear systems. A sufficient conditions are derived to solve the problem by dynamic measurement feedback, i.e. the feedback that depends on measurable outputs only. The solution to the disturbance decoupling problem, described in this paper, is based on the input-output linearization, which is used to linearize cert...
