Disturbance Decoupling for Non-linear Structured Systems
نویسندگان
چکیده
"Astructural approach to the disturbance decoupling problem of non-linear systems is introduced. For this purpose, in analogy to linear systems theory, a structural description of non-linear systems is defined. In associating a directed graph to such a system, two important system properties, the differential output rank and the structure at infinity, can be characterized in terms of inputoutput paths. Based on this concept, the disturbance rejection problem can be easily solved. Moreover, necessary conditions valid for general non structured systems can be defined in a graph-theoretic way. The advantages of this approach are demonstrated by illustrative examples.

Partial disturbance decoupling problem for structured transfer matrix systems by measurement feedback
Partial disturbance decoupling problems are equivalent to zeroing the first, say k Markov parameters of the closed-loop system between the disturbance and controlled output. One might consider this problem when it is not possible to zero all the Markov parameters which is known as exact disturbance decoupling. Structured transfer matrix systems are linear systems given by transfer matrices of w...
متن کاملGeneric decoupling problems for structured time-delay systems
In this paper, linear structured systems with delays are considered. The generic structure at infinity of such systems is defined and used to solve the disturbance decoupling problem and, above all, to bring a new solvability necessary and sufficient conditions to the row by row decoupling problem by generalized state feedback control laws. For the two considered problems, the provided conditio...
متن کاملDisturbance decoupling for nonlinear systems by measurement feedback: sensor location
The paper addresses the problem on sensor location regarding the solvability of the disturbance decoupling problem by dynamic measurement feedback. Three methods are given to find a measured output, which guarantees the solution to the problem. It is also shown that the results for linear structured systems on sensor location when applied to infinitesimal linear representation of nonlinear syst...

Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...
