摘要: Here, we propose a new procedure for output feedback design systems with nonlinearities satisfying quadratic constraints. It provides an alternative the classical observer-based and relies on transformation of closed-loop system dynamic controller particular structure into special block form. Asymptotic stability is shown using Lyapunov theory strictly positive realness circle-theorem approach. The result relevant control analysis Moore-Greitzer models compressor systems.
