Realtime telecontrol of mechanical dynamic information with the Internet is attempted.The author analyses the ingredient causingthe time-delay

measures the time-delay practically

uses the Slide-mode and spline func-tion principles for reference

and substitutes the normal Slide-mode inputswith the mean of the Slide-mode

then adoptsthe RBF (radial basis functions) neural network setting up network time-delay model.The simulation results show thatthe model can effectively substitute the actual network in Internet-based closed loop control system research under time-delay condition;the methods used in the modeling

due tothe virtue of speediness and exactness

is capable of learn andpredict the network time-delay on line

this gives a new idea in Internleet-based remote closed-loop control.
