Robust H ∞ control for a class of uncertain nonlinear switched systems

Dimirovski, Georgi M. (Dogus Author) -- Conference full title: 2012 UKACC International Conference on Control : Cardiff, UK, 3-5 September 2012This paper focuses on the robust H∞ control problem for a class of nonlinear switched systems containing neutral uncertainties with average dwell time (ADT). Uncertainties are assumed to be nonlinearly dependent on state and state derivative and allowed to appear in channels of state, control input and disturbance input. The robust H∞ control problem of the switched system with stabilizable and unstabilizable subsystems is solvable if the stabilizable and unstabilizable subsystems satisfy certain conditions and admissible switching strategy among them. ADT and piecewise Lyapunov function approaches are applied to achieve the control design. A numerical example is provided to illustrate the effectiveness of the proposed results.University of Glamorga
