报告简介：

The estimation problem of unmeasured state and parameters for complex systems is of great importance for applications in control theory. Emerging fields of applications require reliable approaches on estimation designfor diverse classes of dynamical systems. In many areas, as in biology, for example, the intrinsic uncertainty of the models prevents for applications of the conventional estimation approaches. To overcome this obstruction, recent techniques for estimation of uncertain systems have been proposed and developed. Uncertainties may represent unknown inputs/disturbances, noises, parameters or can result from a transformation of nonlinear systems using Linear Parameter-Varying tools, where strong nonlinearities are modeled by uncertain parameters. In some cases an exact estimation of the state is not possible due to a lack of information about uncertainties. In such cases, set-membership techniques can be used to provide not only an approximation but also the set of all admissible values of the state/parameters, which are consistent with the available information. This lecture aims at presenting some recent results for designing methods of interval observers for switched systems.
