✦ Synopsis
A framework is developed for the general nonlinear H output feedback control problem, in which two major restrictions are relaxed, i.e., the non-singular penalty in H cost and the positive definite solution of Hamilton-Jacobi inequality at present state space nonlinear H control literatures. As illustrated in an example, positive semidefinite solution simplifies the structure of the H controller. Based on this framework, some sufficient conditions are derived. While specialized to linear systems, the controller reduces to the so-called central controller.
