The passivity theorem

WebbPassivity-Based Control By the Passivity Theorem, the negative-feedback interconnection of two strictly passive systems and is always stable. When the physical plant is passive, it is therefore advantageous to use a passive controller for robustness and safety reasons. Webbpassivity/finite-gain stability theorem. The hybrid passivity/ finite-gain stability theorem relies on both passivity and small-gain arguments in tandem; when a passive I–Omap exists stability is guaranteed via a passivity theorem type argument, and when a passivity violation occurs bounded plant and controller gains ensure destabilisation ...
