研究了在保持系统极点不变的情况下，对系统的某些极点进行重新分配的问题。该问题可以通过单输入状态反馈控制唯一地解决。通过施加多输入控制力，可以得到部分极点配置问题的一族解。提出了一种确定多输入控制在某种意义上是小的算法。提出的非迭代算法，定义了一个封闭形式的解决方案，其自然二阶形式的部分极点配置问题，没有使用一阶实现。通过数值例子证明了所提出的方法实现的控制工作的减少。
The problem of reassigning some poles of a vibratory system, while keeping the other poles unchanged, is considered. The problem may be solved uniquely by single-input state feedback control. A family of solutions to the partial pole assignment problem may be obtained by applying multi-input control forces. An algorithm for determining a multi-input control which is small in some sense is presented. The non-iterative algorithm proposed, defines a closed-form solution to the partial pole assignment problem in its natural second order form, and no first order realization is used. The reduction in the control effort achieved by the proposed method is demonstrated by numerical examples.
