Disturbance decoupling by measurement feedback

Solvability conditions for disturbance decoupling problems with static measurement feedback

Two well-known disturbance decoupling problems are considered. A checkable necessary and su cient condition is derived under which the disturbance decoupling problem with static measurement feedback (DDPKM) is solvable for a class of multi-input and multi-output linear time-invariant systems, which have a left invertible transfer matrix function from the control input to the controlled output....

Disturbance decoupling of nonlinear MISO systems by static measurement feedback

This paper highlights the role of the rank of a differential one-form in the solution of such nonlinear control problems via measurement feedback as disturbance decoupling prob­ lem of multi-input single output (MISO) systems. For the later problem, some necessary conditions and sufficient conditions are given.

Disturbance decoupling for descriptor systems by measurement feedback

Disturbance 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...

Solutions to general H = almost disturbance decoupling problem with measurement feedback and internal stability for discrete - time systems q

In this paper, we construct feedback controllers, explicitly parameterized in a single parameter e, that solve the well-known H = almost disturbance decoupling problem with measurement feedback and with internal stability (H = -ADDPMS) for discrete-time linear systems. In particular, we explicitly construct parameterized solutions for the following three cases: the full state feedback, the full...
