A systematic comprehensive account is given of the methods and results of theoretical simulation of the dynamics of the processes of collective electromagnetic interaction in a nonequilibrium system formed by an electron beam and an undulator. The physical mechanisms of the phenomena responsible for the emission of stimulated (coherent) radiation are identified for specific nonequilibrium systems belonging to the class of free-electron lasers.
