Title: Zames-Falb multipliers for stability analysis of Lur’e systems
Abstract:
This lecture will introduce Zames-Falb multipliers as a tool to analyse the stability of so-called Lur’e systems: systems which are feedback interconnections of a linear element and a nonlinear static element. The lecture will introduce the ideas behind Zames-Falb multipliers from a classical passivity/absolute-stability perspective, and will cover their derivation. The interesting, but also challenging aspect of Zames-Falb multiplier analysis is that, while stability results can be of vastly lower conservatism than Circle/Popov criteria base approaches, it is difficult to exploit the degrees of freedom offered by the approach in a tractable manner. Therefore, the lecture will also introduce an LMI-based approach for finding sub-classes of Zames-Falb multipliers. The lecture will finish with some exploration of the incomplete aspects of Zames-Falb multiplier analysis.
