Reliable controller design for nonlinear systems

This paper addresses the reliable H-infinity control problems for affine nonlinear systems. Based on the Hamilton-Jacobi inequality approach developed in the H-infinity control problems for affine nonlinear systems, a method for the design of reliable nonlinear control systems is presented. The resulting nonlinear control systems are reliable in that they provide guaranteed local asymptotic stability and H-infinity performance not only when all control components are operational, but also in case of some component outages within a prespecified subset of control components.
