Savkin, Andrey V.Petersen, Ian R.2025-03-242025-03-24Scopus:0030170235https://dspace-test.anu.edu.au/handle/1885/733733488This paper considers the problem of constructing a linear dynamic output feedback controller such that when applied to a given uncertain system, the resulting closed-loop uncertain system is globally uniformly ultimately bounded. The uncertain systems under consideration contain multiple uncertain nonlinearities, each subject to a non-homogeneous norm bound condition. The approach taken is to apply standard results from HK control theory to the problem. The main result is a sufficient condition for the existence of such a controller. This condition is given in terms of the existence of suitable solutions to a pair of parameter-dependent algebraic Riccati equations.This work was supported by the Australian Research Council.5English199610.1080/00207729608929253http://www.scopus.com/inward/record.url?scp=0030170235&partnerID=8YFLogxK
