Reliable guaranteed cost control for uncertain nonlinear systems

Abstract

This paper deals with the reliable control design problem for uncertain nonlinear systems. A more practical model of actuator failures than outage is adopted. Based on the Hamilton-Jacobi inequality approach from nonlinear H/sub /spl infin// control theory, a method for designing reliable state feedback controllers is presented. The resulting control systems are robustly stable and with an H/sub 2/ performance bound against plant uncertainty and actuator failures.
