| Abstract: |
| The H∞ output feedback control problem for a class of large-scale nonlinear systems with time delay in both state and input
is considered in this paper. It is assumed that the interconnected nonlinearities are limited by constant multiplied by unmeasured
states, delayed states and external disturbances. Different from existing methods to study the H∞ control of large-scale
nonlinear systems, the static gain control technique is utilized to obtain an observer-based output feedback control strategy,
which makes the closed-loop system globally asymptotically stable and attenuates the effect of external disturbances. An
example is finally carried out to show the feasibility of the proposed control strategy. |
