However, the successful construction of an internal model (IM) relies on the observability condition of a steady-state generator (SSG). In the literature, the observability condition is restricted to linear or linearized SSGs. This paper introduces a novel observability condition for nonlinear SSGs. Nonlinear observability leads to an effective combination of the internal model principle and the certainty equivalence principle for a more general class of systems. 2012-08-21T02:27:08.107Z ]]> http://nova.newcastle.edu.au/vital/access/manager/Repository/uon:5989 An output regulation problem can be converted into a stabilization problem thanks to an appropriately designed internal model. In literature, the successful construction of an internal model relies on the linear observability condition of the steady state generator. This paper defines the global observability property of the steady state generator, under which the output regulation problem is solved for a more general class of systems. 2012-03-12T06:48:40.468Z ]]> http://nova.newcastle.edu.au/vital/access/manager/Repository/uon:2610 This paper is concerned with a class of continuous time uncertain systems which satisfy a certain Integral Quadratic Constraint. The problems of robust filtering, robust prediction, and robust smoothing for such systems are defined, and nonconservative solutions are given in terms of Riccati differential equations. This paper also addresses a problem of robust observability for this class of uncertain systems. 2010-04-27T06:14:11.984Z ]]>
