The design method of output feedback pole configuration of the structure control system is given. The method adopts some basic steps of robust analysis and design, taking into account the robustness of the structure control system and the simple calculation. Based on the robust metric, the coordination relation between the state vector and the output vector parameter is established. By using the QR decomposition technique, the gain matrix expression of the robust pole assignment problem is derived. By analyzing the expression, the robustness of the proposed method can be obtained Guaranteed. The output feedback pole configuration problem is transformed into the nonlinear least squares problem, and the LM method is used to solve the feedback matrix with the minimum norm. Finally, the method of this paper is applied to the vibration control of a three-layer structure under sinusoidal loading, which proves the performance of the proposed method
