微小型金属壳谐振陀螺幅值稳定控制方法研究

Research on amplitude stability control method of microminiature metal⁃shell resonance gyro

针对金属壳谐振陀螺振子小型化设计,电极控制力过小导致响应时间慢的问题,传统四回路PI控制难以有效解决,提出一种微小型金属壳谐振陀螺幅值控制方法,有效提高响应速度。在分析微小型金属壳谐振陀螺工作原理的基础上,对传统四回路PI控制器进行研究,提取幅值作为被控对象,设计微分先行控制器,搭建算法仿真平台。通过仿真验证,文中方法比传统四回路PI控制方法响应速度提高,角速率解算时间缩短。

As it is difficult for the traditional four⁃loop PI control to effectively solve the problem of slow response sped caused by insufficient electrode control force in miniaturization design of the metal⁃shell resonance gyro,an amplitude control method of microminiature metal⁃shell resonance gyro is proposed to effectively improve the response speed.On the basis of analysis on the working principle of microminiature metal⁃shell resonance gyro,the traditional four⁃loop PI controller is studied,the amplitude is extracted as the controlled object,the differential advanced controller is designed,and the algorithm simulation platform is built.The simulation results show that,in comparison with the traditional four⁃loop PI control method,the proposed method has higher response speed and shorter angular rate solving time.
