In this paper we consider several interconnected ISS systems supplied with ISS Lyapunov functions defined in the dissipative form. Our aim is to construct an ISS Lyapunov function for the interconnection. We provide a condition of a small gain type under which this construction is possible and describe a method of an explicit construction of such an ISS Lyapunov function.
This paper provides sufficient conditions for both practical stability and finite time stability of linear singular continuous time delay systems which can be mathematically described as Eẋ(t) = A0x(t) + A1x(t − τ). Considering a finite time stability concept, new delay independent conditions have been derived using the approach based on the Lyapunov-like functions and their properties on the subspace...
This paper presents the analysis of a current control system to PMSG in overmodulation region. A detailed review of the space vector modulation in over-modulation region is initially presented. Then, an anti-windup method for current controller of PMSG is proposed. The equilibrium points of the closed loop system are calculated and an estimation of the region of operation with guaranteed stability...
