The passivity theorem

Webb6 dec. 2016 · The storage function in the case of the passivity supply rate often has the interpretation of a (generalized) energy function, and \(S_a(x)\)equals the maximalenergy that can be extracted from the system being in state x, while \(S_r(x)\)is the minimalenergy that is needed to bring the system toward state x, while starting from a ground state … 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.

By doing so, we extend the applicability of the theorem beyond semi-sectorial systems, and recover the frequency-wise results in [5], [6] for LTI systems. The proposed theorem also extends the passivity theorem when the open-loop systems are causal and stable. Specifically,
