谐振式陀螺全角模式误差来源与接口技术

全角模式是谐振式陀螺的新型接口技术，具有直接测量角度、动态范围大的优点，但其对陀螺元器件对称性要求极高的缺点限制了它的实际应用。首先，从谐振式陀螺全角模式的原理出发，讨论了各种不理想因素对全角模式运行造成的问题。然后，从器件设计和控制系统两方面出发，讨论了可行的技术路线。最后，通过数值仿真的方法证明了理论分析的正确性，并给出了谐振式陀螺的选型和控制系统的建议。

Error Source and Interface Technology of Resonant Gyroscope with Whole Angle Mode

The whole angle mode is a new interface technology of resonant gyroscope, it has the advantages of direct measurement of angle and large dynamic range. However, its high requirement for symmetry of gyroscope components limits its practical application. In this paper, based on the principle of whole angle mode of resonant gyroscope, the problems caused by various unsatisfactory factors in the operation of whole angle mode are discussed. Then, from two aspects of device design and control system, the feasible technical route is discussed. Finally, the correctness of the theoretical analysis is proved by numerical simulation, and suggestions for the selection and control system of resonant gyroscope are given.
