Abstract :
In this paper, a novel relation between the weighting matrix Q in LQR and an eigenstructure of the desired closed-loop system is proposed. The method of the transformation matrix via a controller is utilized to develop the scheme. Using the proposed algorithm, the state feedback gain with the desired eigenstructure in the LQR can be obtained. The proposed scheme is applied to designing an automotive active suspension control system to show the usefulness of the proposed scheme
