Abstract: Aμanalysis andμsynthesis method for nonlinear robust control systems was presented. The nonlinear robust contrl problem usingμmethod was described. By means of the nonlinear state feedback and state coordinates transformation, many uncertain nonlinear systems can be transformed as a linear fractional transformation (LFT) on the generalized plant and the uncertainty. Based on the LFT, a linear robust controller can be obtained by theD-Kiteration and then a corresponding nonlinear robust control law is constructed. An example was given in the paper.
