本文讨论了非线性系统参数扰动对输入输出解耦的影响。通过对一类参数扰动进行刻画,得到了这类参数扰动下,静态反馈闭环系统仍保持无交互控制,且输出不受影响的充要条件,然后讨论了系统同时存在输入扰动时干扰解耦问题可解的条件。
In this paper, the influence of nonlinear system parameters disturbance on the input and output decoupling is discussed. By describing the perturbation of a kind of parameters, the necessary and sufficient conditions are obtained that the static feedback closed-loop system remains non-interactive and its output is unaffected under the perturbation of such parameters. Then, the decoupling problem of the interference when the input disturbances exist simultaneously Solvable conditions.
