摘要:

该文考虑 Banach 空间中 Riemann-Liouville 分数阶微分发展控制系统的逼近能控性. 首先, 证明 Riemann-Liouville 分数阶微分发展方程在 Banach 空间中存在 $C_{1-\alpha}$-温和解. 其次, 在合理的假设条件下证明 Riemann-Liouville 分数阶微分发展控制系统是逼近能控的. 最后给出一实际例子来验证该文的主要结果.

关键词: Riemann-Liouville 发展微分系统, $C_{1-\alpha}$-温和解, 存在性, 逼近能控

Abstract:

In this paper, We discuss Riemann-Liouville fractional evolution differential systems in Banach spaces. Firstly, the existence of $C_{1-\alpha}$-mild solutions for the Riemann-Liouville fractional evolution differential equations are established in Banach spaces. Secondly, we make some general assumptions to guarantee the approximate controllability of the associated Riemann-Liouville fractional evolution systems is also formulated and proved. In the end, an example is given to illustrate our main results.

Key words: Riemann-Liouville fractional evolution differential systems, $C_{1-\alpha}$-mild solutions, existence, approximate controllability
