Summary:A generalized eigenstructure assignment procedure for designing a controller that has the best eigenstructure achievable while simultaneously maintaining stability robustness to time-varying parametric variations is presented. The approach taken is the constrained minimization of the difference between the actual and desired eigenstructure. The minimization is made subject to the constraints of the eigenstructure equation and the closed-loop Lyapunov equation. The capability of the formulation is illustrated in the design of a mode-decoupling roll-yaw autopilot for a generic, non-axisymmetrical airframe.< >
