The investigation of quantum-classical correspondence may lead to gain a\ndeeper understanding of the classical limit of quantum theory. We develop a\nquantum formalism on the basis of a linear-invariant theorem, which gives an\nexact quantum-classical correspondence for damped oscillatory systems that are\nperturbed by an arbitrary force. Within our formalism, the quantum trajectory\nand expectation values of quantum observables are precisely coincide with their\nclassical counterparts in the case where we remove the global quantum constant\nh from their quantum results. In particular, we illustrate the correspondence\nof the quantum energy with the classical one in detail.\n
