In order to make the procedure of derivation aiming at the elements, but not the whole matrix of the state feedback, a simplified technique is used in the middle tache to avoid the complicated of matrixes in ather known methods.

• 为计算方便，在原有方法的基础上，对中间环节采用简化的处理办法，使之针对状态反馈矩阵的元素而非整个状态反馈矩阵求解，因而避免了前人方法中出现的复杂的矩阵运算，减小了计算量。
