一类热方程扰动系统的能控性
Controllability for a class of heat equations with perturbations
【摘要】 研究了一类热方程扰动系统的能控性问题.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.
【Abstract】 This paper is concerned with the controllability problem for a class of heat equations with perturbations.First,approximate controllability for the perturbed system is provided.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.At last,the null controllability of the system is given.
