对求解齐次AX+XB=0方程非奇异解的研究,可以有效解决二阶系统解耦问题。但高阶系统无法通过正常的计算方法找到非奇异解,而且误差很高。针对由二阶系统变形来的AX+XB=0方程,并对其具有的特殊形式进行研究探讨,找到解的构造方法,从而更加准确的找到其非奇异解,将二阶系统进行有效的解耦,数值试验证明了该方法的可行性。

The research of nonsingular solution of the AX+XB=0 equation solution can ef-fectively solve the decoupling problem of second order system .However , high-order system cannot find the singular solution through the calculation method of normal , and the error is very high .In this paper , by the deformation to the equation of second order system with spe-cial form of research , the solution of the method was found , which was more accurate to find the singular solution , and effectively decouple the second -order system.The results of nu-merical experiments showed this constitution method was a feasible one , which supplied a simple approach for nonsingular solution of the Sylvester equation .
