Abstract
Control of systems with time-varying dynamical characteristics impose either a conservative time-invariant control strategy that should hold for all time instants or to adopt some adaptive scheme. One of such, called simple adaptive control, is particularly appropriate for control applications such as flexible aircrafts or other fast varying processes. Indeed, it does not need any real-time estimation of timevaying parameters but adapts based on the unique sensors measurements. Yet, this control strategy, also called passivitybased adaptive control, needs to be applied for the system to be passifiable. Or at least it needs to exhibit a linear combination of the inputs and outputs such that this property holds. The paper is devoted to the search of such linear combinations with practical efficient algorithms. Results are discussed in detail for an uncertain time-varying aircraft control example.

Abstract
Slack variables technique for parameter-dependent robustness analysis of polytopic systems has emerged about ten years ago and has spread for many stability and performance problems. One of its main advantage is the simplicity of use but it has the drawback to generate LMI problems with large number of decision variables are large sized constraints. The paper is devoted to the study of ways to limit this numerical burden while controlling the conservatism. The study is lead in the context of Integral Quadratic Separation thus covering a very large class of robust performance analysis problems.
