摘要
研究了一种新型的混合式陀螺仪,它既具有实现传统动力调谐陀螺仪较高精度的潜力,又具有硅微陀螺仪体积小、价格低等优点。混合式陀螺仪以电容极板实现差分电容检测和力矩反馈的技术替代传统动力调谐陀螺仪的信号器及力矩器。以再平衡回路技术为基础,建立了混合式陀螺仪闭环检测系统。与开环检测相比,闭环检测系统具有输出信号线性度较好、检测带宽较宽的优点。进行了系统开环和闭环情况下的频率特性仿真。对混合式陀螺仪进行了初步实验,结果验证了方案的可行性。
Described in this paper is a hybrid gyroscope with advantages not only in the potentiality of achieving high precision like the tradition dynamically tuned gyroscope（DTG）,but also in small size and low cost like the Silicon Micro-machined Gyroscope（SMG）.Instead of using signal converters and actuator in traditional DTG,the hybrid gyroscope uses capacitor plate to achieve the differential capacitive sensing and torque feedback technique.The hybrid gyroscope closed-loop detecting system is based on rebalance loop.The closed-loop detecting system has advantages of better output signal linearity and wider detecting bandwidth compared with open-loop system.The frequency characteristics of the open-loop and closed-loop systems are simulated.Experimental result illustrates that the proposed scheme is feasible.
