We theoretically study the use of a dynamic Lorentzian reservoir environment to realize contro of the evolution of an excited two-level atom. It is found that the change of Lorentzian reservoir leads to the interaction between the electromagnetic modes in the cavity and those outside, resulting in the redistribution of the electromagnetic modes density. When the frequency of reservoir change is consistent with the process of exchange of energy between the atom and environment, a relatively stable coherent evolution can be obtained, and the decay is obviously inhibited.
