一类具有Riemann-Liouville 分数阶导数的线性时不变微分系统的完全能控性

his paper is concerned with the complete controllability of a fractional linear time-invariant differential system with Riemann-Liouville derivative. The solution of the state equation with classical initial value is first derived. Then two criteria on controllability for the system, which are sufficient and necessary, are established. Two examples illustrate the results.
