Design and performance experiment of vehicle-borne strapdown 3-DOF stabilization platform

Based on the configuration feature and function demand of vehicle-borne line-of-sight (LOS) stabilization platform, a strap-down stabilization platform system was schemed. Combined with communication protocol between upper computer and lower computer of the stabilization platform control system, adopted the multithread and multimedia timer technology, an upper computer soft was compiled with visual C++, which was used to acquire and send gimbals position information real-time. To validate the real-time communication function of platform control system, the dynamic performance test was carried out. The results indicate that the real-time communication capability of stable platform control system satisfie semploy requirements.
