On robust nonlinear H/sub /spl infin// control problem with matched parameter uncertainty

摘要

This paper addresses robust H/sub /spl infin// control problem for nonlinear systems with matched parameter uncertainty. The necessary and sufficient conditions for existence of global strong robust H/sub /spl infin// dynamic compensators are obtained based on nonlinear matrix inequality approach. It reduces a robust H/sub /spl infin// control problems to a standard H/sub /spl infin// problem for an auxiliary nonlinear system.
