Observer‐based decentralized robust H output tracking control with preview action for uncertain and disturbed nonlinear interconnected systems

Abstract: The problem of observer‐based decentralized robust H∞ output tracking control with preview action in a class of uncertain and disturbed nonlinear interconnected systems is investigated in this study. The considered interconnected system consists of several subsystems with nonlinear interconnections, parametric uncertainties, and external disturbances. Based on the augmented error system approach combined with Lyapunov stability theory and special matrix inequality linearization techniques, a sufficient conditi… Show more

“…Remark The existing literature requires restrictions on the nonlinear function fij()t,xifalse(tfalse),xjfalse(tfalse),xi()tprefix−μij,xj()tprefix−τij$$ {f}_{ij}\left(t,{x}_i(t),{x}_j(t),{x}_i\left(t-{\mu}_{ij}\right),{x}_j\left(t-{\tau}_{ij}\right)\right) $$ when investigating nonlinear interconnected systems by means of decentralized control. For example, the References 27 and 28 requires that the nonlinear function satisfies the Lipschitz condition. However, in our article, as long as the form of the nonlinear function is known, it can be used to design the controller without any additional restrictions.…”

“…Reference 26 investigated the problem of preview control for a class of discrete‐time interconnected systems by using decentralized control. In References 27 and 28, the observer‐based decentralized output feedback preview tracking control methods were proposed for nonlinear interconnected systems. Reference 29 tackled the design problem of preview tracking controller for singular interconnected systems.…”
