coherent control

n.
The use of coherent radiation, such as that generated by a laser, to change the behavior of atomic, molecular, or electronic systems, often to alter the likelihood of a chemical reaction.

The basic idea of the hybrid impulsive control is to divide the control into a piecewise continuous open-loop coherent control [u.sub.1](t) and an impulsive control [u.sub.2] x [u.sub.1](t) design is similar to the traditional Lyapunov control which drives states to invariant sets.
