This paper reviews key aspects of the problem of magnetic islands control byelectron cyclotron current drive in fusion devices. On the basis of the ordering ofthe basic spatial and time scales of the magnetic reconnection physics, we presentthe established results, highlighting some of the open issues posed by the small-scalestructures that typically accompany the nonlinear evolution of the magnetic islandsand constrain the effect of the control action.
