Analysis and Synthesis for Robust H-infinity Control of Uncertain Nonlinear Systems
不确定非线性系统的鲁棒H∞控制分析与综合

The paper deals with the robust H-infinity control problem of a class of affine nonlinear systems. For the systems where there exist additive uncertainties in the free system, the external disturbance input matrix and the control input matrix, analysis and synthesis of robust performance are reduced to solving a set of Hamilton Jacobi inequalities. Sufficient conditions for guaranteeing the nonlinear control system to meet the robust disturbance attenuation performance are given, and the formulation of the nonlinear robust controller is obtained in this paper. A simulation example shows the correctness of the conclusions proposed.
