In this paper the design of robust H2-estimators for the class of linear systems that depend rationally on ratebounded uncertain time-varying parameters is addressed. The uncertainties are characterized by dynamic IQCs and new LMI conditions are formulated that allow for a nontrivial extension of the estimation problem with a weighting filter at the output.(More)
Robust stability analysis problem is considered for the feedback inter-connection of a causal and stable linear time-invariant system with causal and stable linear time-varying block-diagonal structured uncertainties having sub-blocks of bounded norms and variation rates. The problem is studied within the recently developed IQC framework of robust stability(More)
