Abstract：Stable platform is a kind of stabilizing on image stabilization, target tracking, image stabilization testing instrument with isolation and other functions. Stable platform includes angular rate measurement systems and servo loop stability control system, and it covers automation and control, electronic science and other disciplines of knowledge. A multifunctional micro-electro-mechanical systems (MEMS) gyro-stabilized platform with the experimental teaching undergraduate background was designed, and its main control functions was to achieve a stable platform and turntable testing. Firstly, based on the current situation of domestic and foreign research status and application of stable platform, the multifunctional MEMS gyro-stabilized platform mechanical was designed to realize the gyro-stabilized platform and turntable function test stable platform; secondly, the hardware platform of stable control system was designed combined with the platform technical indicators; finally, the static and dynamic tests were carried out with the platform placed on the non-magnetic turntable. The results showed that the platform could meet the stabilization accuracy requirements of 1° under static attitude, and this proved the reasonability of the performance indexes of the designed stable platform.
