Abstract: The H∞ robust control problem of a class of uncertain nonlinear systems with engineering background is researched. Based on Hamilton-Jacobi inequality, a sufficient condition is presented such that the class of nonlinear systems is asymptotically stable and its L2-gain is limitable. Under the condition, a state feedback controller is given such that the close-loop systems statisfy H∞ robust disturbance attenuation performance. -
