Abstract :
This paper addresses the robust H∞ control system design problem for nonlinear systems under degradation of actuators and sensors. The degradation of actuators and sensors is modeled by a scaling factor with upper and lower bounds. Design methods are presented for both state feedback and dynamic output (measurement) feedback in terms of solutions of Hamilton-Jacobi inequalities. The designed controller is such that the closed-loop system is robustly stable and has an L2 gain bound against to the degradation of actuators and sensors
