Micro electro mechanical system (MEMS) gyroscope is an important application of MEMS technology in inertia type instruments. It has the advantages of small volume, light weight, low cost, mass production and good impact resistances. It has important practical value and wide application prospect in national economy and national defense and military fields. In particular, the double mass line vibration structure is the main research object of domestic and foreign scientific research institutes. Although the precision of silicon micromechanical gyroscopes has been improved significantly in recent decades, its static and dynamic performance still cannot meet the requirements of medium and high precision fields due to various factors, including the deterioration and drift of gyroscope output signal caused by machining errors: The contradiction between mechanical sensitivity of gyro structure and gyroscope bandwidth; The detection modal dynamic performance needs to be further improved; the temperature characteristics of MEMS gyro are poor. For this purpose, the author compiled this book according to the latest development, and combined it with his research and engineering practice in the field of dual-mass linear vibration silicon-based MEMS gyroscope.
