To design a reduced-order controller with loosing little accuracy.

    Design/methodology/approach

    Singular perturbation approach by quasi-steady state approximation and by Matrix block diagonalization technique is used.

    Findings

    It is shown that few errors occur between the uncorrected and corrected solutions for the fast subsystems while a few errors occur between the two kinds of solutions for the slow subsystems. The uncorrected solution is admissible for most dynamics. If not, it is recommended that the corrected solution be used.

    Research limitations

    Proportional feedback control gain is obtained by Pole placement method, which may produce an unwanted overshoot in the response.

    Originality/value

    This paper shows that the corrected controller is successfully applied in the aircraft dynamics and control.
