The project of much-anticipated LAMOST (Large sky Area Multi-Object fibre Spectroscopic Telescope) has successfully been inspected and accepted at national-level evaluation. It will become the world’s most powerful meter-class level ground astronomical optical survey telescope. The ever-ambitious project throughout the development history of Chinese astronomical optics telescopes has brought an extraordinary challenge to its control system from all-round aspects. Painstaking effort has been made to the R&D of the control system from its design strategy, functionality analyses to most subtle technical solutions, and of course efficient engineering management is also included. A number of papers highlighting the anticipated LAMOST control system have previously been published during the course of the project evolving. However, much lesson and experience have been learned since 10 years ago. Now the telescope with all its facilities and observation chamber has been put into trial observation. This is the time to review the past and ponder over the future of the control system as a whole against the functional telescope in current reality. Lesson and experience are discussed. Some considerations for improving the system efficiency and the accessibility are presented too in this paper.
