Research Of The Dynamics Model And Compensation Laws Of The Light Guidance System

Carrier-based aircraft landing process is a crisis-ridden process, as a result of large sailing ships to change their original flight routes, and constantly shaking the landing deck, as well as by other effects of external interference makes aircraft landing more difficult than stable land landing.One of the most dangerous stages is landing. Today the majority of large ships use light assist landing device, which help to provide an optic slide runway. However, due to the large ships shaking which made by the waves, the system also have caused changes in slide runway. In order to reduce the stability of the system and to provide a stable optical glide slide runway, the lighting stability system will compensate the movement brought about by changes in slid runway.In this paper, in order to enhance the safety of aircraft landing for the purpose, I design the guided laws of the lighting stability system, establish a stable platform with two degrees of freedom dynamic model, and imitate the whole system in virtual reality simulation. The study ensures the safety of aircraft landing.First of all, in this paper, the character of the today's light system used in large ships is analyzed, on the basis of the systematic structure, it also clarifies the function of stabilized system and several requirements for the system, which lay the function for the next chapters.Secondly, in order to improve the operation reliability of manual carrier landing system, with the purpose of landing security when the landing environment is poor, I study the compensation laws of the light stabilized system, offered the angle of the point stabilized program, then analysis and validate the program. Established the dynamics model of the system, analyzed the characters of the stabilized system's moving. I offered the attitude angles of the stabilized system through the study of the ship's moving and the system's moving. According to the characters of the stabilized system and the influence from the ship, I amended the compensation law. and made the whole system model more perfect. Finally, 1 used the VRML programming language to make the virtual simulation of the whole system model, get a cleared and virtual result of the simulation, and analysis the simulation curves to ensure the system model is right.
