The robust control problem for a class of uncertain nonlinear system was concerned, in which the system could be expressed as the linear combination of a differentiable unknown vector that was linearly bounded. After the quadratic stability properties of the system was analyzed, the necessary and sufficient conditions of quadratic stability for the system were given. The design method of robust linear state feedback controller for the system was presented to make the system quadratically stable. Simulation result for a simple example shows correctness and effectiveness of the design method for robust control.
