The performance of a multivariable control system is limited by intrinsic properties (such as right-half-plane poles/zeros and condition number) of a plant, hence a required performance of a control system is achievable only when a plant is properly designed to fit the need of a control engineer. Such a plant is sometimes referred to as an ＇(input-output) controllable plant＇, and is referred to as a control-configured-plant (CCP) in this paper. However, due to the lack of a systematic approach, existing CCPs (such as the T2-CCV and the AO-IAF ＇Mohawk＇ airplanes) are highly ill-conditioned with lightly damped RHP poles/zeros. As a result, it is extremely difficult to achieve a good control performance with such plants. Motivated by these facts, this paper presents a general approach to the design/redesign of a multivariable CCP, which attempts at a plant S(A, B, C) which satisfies constraints on its pole/zero locations and conditioning numbers of G(s) = C(sI - A) (- 1) B in a frequency range, while the H-2 norm of G(s) is maximised. An illustrative example is given to show that a CCP resulting from the present approach can achieve a much better control performance than an ＇ordinary＇ multivariable plant.
