| 摘 要： | 在１９８１年韩京清发表的论文＂线性系统的结构与反馈计算＂的基础上发展和完善了基于高阶微分方程输入－输出描述的非线性系统直接反馈线性化（ＤＦＬ）理论。给出了ＤＦＬ问题的有解条件和补偿器的结构。首次提出了＂隐动态＂（ＨＤ）概念,并证明了它与微分几何非线性控制理论中的＂零动态＂（ＺＤ）的等价关系。该法所需数学工具简单;保留了原状态变量的物理意义,便于工程应用。

| Abstract: | Based on the conception of Han Jingqing's paper "Structure of linear control systems and computing problem of feedback systems"published in 1981, the direct feedback linearization (DFL) theory for nonlinear control systems described by the input-output higherorder differential equations was well developed in this paper. The solvability condition of theDFL problem and the structure of the DFL-compensator were given. The concept of the hidden dynamics (HD) was proposed for the first time, and it was proved that the HD is equivalent to the zero dynamics (ZD) of the differential geometric theory of nonlinear control. Especially this method is a better one for engineering application, because the mathematics instruments are simple and the physical information of the system can also be preserved. |
