Robust Flight Control Design with Eigenstructure Assignment

摘要

Although the H_∞ control method is a powerful tool to design robust controller, it is difficult to attain the performances in time domain. A new design method of H_∞ state feedback controller is proposed which guarantees the robust stability and assigns eigenstructure in the desired regions. Conditions of robust stability and closed loop eigenstructure assignment are solved in LMI form with one nonlinear constraint. This method is validated with numerical example of flight control design.
