摘　　要：首先以闭环幅频特性的零频特性、固有频率、平方面积和最大幅值4项特征作为控制系统的期望指标集,将状态反馈转化为一组矩阵不等式的可行解问题;然后利用迭代线性矩阵不等式(ILMI)技术求解状态反馈系数;最后通过数值算例说明所给出设计方法的有效性.Four frequency response characteristics, zero frequency characteristic, average bandwidth, area and maximum range value, are denoted as the desired indices for the design of control system. The state feedback problem is transformed to the feasible problem of a set of matrix inequalities, which is solved by using the iterative linear matrix inequality technique. Finally, a numerical example is given to demonstrate the effectiveness of the proposed method.
