UAV is widely applied to a variety of areas, for the huge advantages of remote controlling flight trajectory, iterant recovery and flexible mission payloads flight. The routine design methods for aerocraft control system cannot supply desire of UAV high accuracy flying and replying diversified compositive disturb. System composition and departmental function of UAV flight control system were introduced. An online interaction simulation method of UAV flight control system was advanced. The principle and principle of online interaction simulation were analyzed. The key techniques of constituting fiducial simulation model, real time updating and revising simulation model, on-line detecting a mass of data, were researched which needed resolving by online interaction simulation method. Distinguishing exception and auto-warning for UAV flight were achieved, providing technique support to achieve assistant decision-making and intelligent control function of UAV.
