摘要
This paper is concerned with stabilisation and disturbance attenuation problems for linear systems with uncertain parameters. We consider the case, where the uncertainties are possibly unbounded but have a certain normal distribution and the case, where the uncertainties are arbitrary but bounded. Criteria for the solvability of the disturbance attenuation problem are presented in terms of generalized Riccati-type matrix inequalities and equations. The main part of the paper is devoted to the analysis and solution of these equations. A numerical example is given to illustrate our results. © 2001 Elsevier Science Inc. All rights reserved.
