An approach for output feedback eigenstructure assignment(EA) of linear multivariable system with parameter uncertainty was presented based on stochastic robustness analysis (SRA), which was used to solve the problem of the eigenstructure robustness. With SRA, the robustness measures of closed-loop control system could be achieved accurately. And the direct relationship between the control system design specifications and the design parameters was established. The optimization algorithm was employed to maximize the control system robustness through trading off between the stability and the performances. At last, SRA-EA was applied to the decoupled design for lateral control system of the hypersonic vehicle. The numerical simulations demonstrated the effectiveness of the presented approach.
