本文提出了一种利用对偶观测器实现多输入系统干扰抑制的控制系统设计方法。该方法将我们以前的工作推广到更一般的情况，并具有以下优点。(1)对偶观测器可以在状态空间中构造任意维数的不可观测子空间。(2)在严格多输入系统中，不可观测子空间的极点可以任意分配。因此，根据该方法构造的不可观测子空间，可以构造出抗干扰系统。在这方面，所构造的控制系统的有效性是通过三质量弹簧系统的数值仿真。
In this paper, a design method of control systems which achieves disturbance rejection for the multiple-input systems using a dual observer is proposed. This method is extended our earlier work to more general case and has the following advantages. (1) An unobservable subspace of arbitrary dimension in the state space could be made by dual observer. (2) In strictly multiple-input systems, poles of the unobservable subspace could be assigned arbitrarily. Therefore, according to the construction of the unobservable subspace using this method, the disturbance rejecting systems could be constructed. In this regards, the validity of constructed control system is shown by the numerical simulations for 3-mass spring system.
