一个自动控制专业的实用程序。以一个四阶系统为例，对任意的参数矩阵 研究其反馈镇定性，通过因式分解法，得到所有能镇定G的 一般形式的K值，用matlab进行了仿真。-Automatic control of a professional utility. A fourth-order system as an example, the parameters of any study the feedback stabilization of the matrix, and through the factorization method, by all G to calm the general forms of K values, using matlab simulation.
