摘要
研究非线性系统零动态的对称性 ,证明了 ,如果非线性系统具有对称性 ,那么 ,它的零动态也具有对称性。局部零动态总可延伸到半全局的零动态 ,而且保持对称性。
Symmetries of zero dynamics of nonlinear systems are studied in this paper.A zero dynamics of a nonlinear system with symmetries is shown to have symmetries.Also,it is always possible to extend a local zero dynamics to a semiglobal one which still possesses symmetries.
