Eigenstructure Assignment Methodology with LQR Characteristics and Application to an Automotive Active Suspension Control

LQR 특성을 갖는 고유구조 지정 제어기법 및 자동차 능동 현가장치 제어에의 응용

In this paper, a new control system design algorithm, which has the advantages of the existing LQR and eigenstrcture assignment methods, is proposed. The method of the transformation matrix via block controller is utilized to develop the scheme. Using the proposed algorithm, LQR weighting matrices q and R, which satisfy the desired closed-loop eigenvalues and eigenvectors, can be achieved using only simple matrix computations. The usefulness of the proposed scheme is verified by applying to a numerical example and an automotive active suspension control system design.
