摘      要：For quantum state trajectory tracking of density matrix in Liouville equation of quantum systems,with the help of concept in quantum system control,one can apply unitary transformation both to controlled system and free-evolutionary target system such as to change the time-variant and non-stationary target system into a stationary ***,the quantum state trajectory tracking problem becomes a steering *** steering control law of the system transformed is designed by means of the Lyapunov stability ***,numerical simulation experiments are given for a five-level energy quantum *** comparison analysis of original system s trajectory tracking with other method illustrates the advantage in control time of the method proposed.
