We introduce a generalization of the Kuramoto model by explicit consideration of time-dependent parameters. The oscillators' natural frequencies and/or couplings are supposed to be influenced by external, time-dependant fields, with constant or randomly-distributed strengths. As a result, the dynamics of an external system is being imposed on top of the autonomous one, a scenario that cannot be treated adequately by previous (adiabatic) approaches. We now propose an analysis which describes faithfully the overall dynamics of the system.
