This paper summarizes the advance in the study of a class of special identification problem, i.e.,the closed loop identification problem. First, the background of the problem and corresponding classical solutions are introduced. Then, several representative classes of closed loop identification methods in the papers of recent years are surveyed and compared with each other, in the same time, their relevance with classical ones is pointed out. Also, the present state of the attractive field: iterative combined design of identification and control ,which is potential for closed loop identification application, is introduced. Finally, some proposals for further research are made.
