Savkin, Andrey V.Petersen, Ian R.2026-07-032026-07-030005-1098ORCID:/0000-0003-4856-9450/work/219177677https://hdl.handle.net/1885/733812649This paper introduces a problem of robust control with a terminal state constraint. This problem involves finding an output feedback controller to steer the initial state of a given system into an ellipsoidal bounding set in a specified time. The underlying system in this problem is a time-varying uncertain linear system in which the uncertainty satisfies an integral quadratic constraint. Necessary and sufficient conditions are given for the solution to this problem in terms of a pair of parameter-dependent Riccati differential equations.5enControllabilityH controlRobust controlTerminal controlTime-varying systemsUncertain linear systems199610.1016/0005-1098(96)00047-70030192927
