This paper studies the H control problem for a nonlinear large-scale system with unknown disturbance. In the large-scale system, each subsystem “without” nonlinear interconnections and disturbance is transformed into a T-S fuzzy system. Moreover, based on a linear decomposition, the nonlinear interconnection corresponding to each subsystem is decomposed to a linear weighting interconnection wh...

This paper concerns a study on the optimal control for nonlinear systems. An appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach. In this fashion, the nonlinear system has been linearized using input-output feedback linearization (IOFL). Then, by utilizing the well developed optimal control theory of linear systems, the compensated ...

This paper presents an approach for the solution of a zero-sum differential game associated with nonlinear state-feedback H∞ control problem. Instead using approximation methods solving corresponding Hamilton–Jacobi–Isaacs (HJI) partial equation, we propose algorithm that calculates explicit inputs to dynamic system by directly performing minimization simultaneous maximization same objective fu...
