摘　　要：文章主要研究了用数学计算方法解决状态向量不能完全测量时的控制问题,在系统输出信息缺失一个的状态下,仍能计算出反馈矩阵K,使得系统的特征根配置在所需的极点处。将不完全信息状态的极点配置问题与ITAE标准型结合,对一维系统进行研究。多维系统的矩阵可等价为两个一维矩阵的乘积形式,从而将多维系统在信息不完全状态下的控制问题转化为一维系统的控制。以某型飞机为例对其横侧向系统在着陆状态时的信息不完全情况下的模态控制方法进行了研究。研究结果表明,用此种方法进行控制后系统具有较好的稳定性和鲁棒性。We use the mathematical method to solve problems for a flight control system when its state vector cannot be measured completely. Sections 1 through 5 of the full paper explain the design method mentioned in the title, which we believe is new and better than existing ones. Their core consists of： （ 1 ） when one piece of output infor- mation on the flight control system is lacking, we can calculate the feedback matrix K to configure its eigenvalues to the required poles; （2） we only study a one-dimensional system by combining the pole configuration with the ITAE standard type because the feedback matrix of a multi-dimensional system controller can be made equivalent to the product of two one-dimensional matrixes; thus, we convert the control problem of a multi-dimensional system with incomplete information into that of a one-dimensional system ; （ 3 ） we apply our new method to the design of the lat- eral-directional system of a certain airplane in its landing state. The simulation results, given in Figs. 1 and 2, and their analysis show preliminarily that the flight control system designed with our new method has good control robust- ness and dynamic properties.
