Query: Minimal modified energy control for fractional linear control systems
  with the Caputo derivative   Fractional control systems with the Caputo derivative are considered. The
modified controllability Gramian and the minimum energy optimal control problem
are investigated. Construction of minimizing steering controls for the modified
energy functional are proposed.
