Disturbance decoupling of multi-input multi-output discrete-time nonlinear systems by static measurement feedback
2012
Proceedings of the Estonian Academy of Sciences
Preserved Fulltext
This paper addresses the disturbance decoupling problem (DDP) for nonlinear systems, extending the results for continuous-time systems into the discrete-time case. Sufficient conditions are given for the solvability of the problem. The notion of the rank of a one-form is used to find the static measurement feedback that solves the DDP whenever possible. Moreover, necessary and sufficient conditions are given for single-input single-output systems, as well as for multi-input multi-output systems under the additional assumption.
