- About this, here we have a discussion about two hands of the controllability of the system, the non-controllability and the exact null controllability. 关于此问题,这里主要讨论系统的不可控性及精确零能控性。
- Exact null controllability 精确零能控
- At last,the null controllability of the system is given. 最后给出系统零能控的结论.
- This means that using the null control character as a field or row terminator is different than having no field or row terminator at all. 这表示使用空控制字符作为字段终止符或行终止符与根本没有字段终止符或行终止符是不同的。
- Then,the system is linearized by variational approach,the local null controllability is proved by applying a generalized implicit function theorem and combining the property of the solution mapping. 首先得到了系统的逼近能控性;然后采用变分方法对系统线性化,再结合解映射的性质,应用推广的隐函数定理,证明系统的局部零能控性;最后给出系统零能控的结论。
