发明背景 本发明通常和二阶系统相结合,更具体地讲,它涉及到现代飞机,导弹等飞行器上使用的象陀螺这样的传感器。本发明详细地叙述了速率陀螺仪阻尼随温度变化的电补偿措施。各种精密仪表为了精确地工作都需要阻尼,尤其是象陀螺仪,加速度计和其他各种利用质量运动测量速度或其他功能的传感器更需要阻尼。陀螺仪安装在充满油或者其他液体的壳体里,就是一个例子。 遇到最难的问题是液体粘度。例如硅油的粘度随环境温度而变化。阻尼液粘度的任何变化都将改变阻尼比,从而引起一个测量误差输出信号。例如角速率输入到速率陀螺仪中就是如此。从前这方面的技术,包括温度或阻尼补偿的若干机械装置,就是用以达到减小陀螺阻尼变化的影响,得到常值阻尼力。 然而,在所有这些系统中,补偿随温度变化引起的阻尼（比）变化,都需要复杂而昂贵的机械装置。同以前的技术相反,本发明采用电子线路用于直接补偿同温度引起的阻尼变化成比例的输出信号,从而基本上取消了以前用的温度或阻尼补偿机械装置。
BACKGROUND OF THE INVENTION The present invention is generally combined with a second order system and, more particularly, it relates to sensors such as gyroscopes used on modern aircraft, missiles and other aircraft. The present invention describes in detail the electrical compensation of rate gyro damping with temperature. Damping is required for precision instruments to work accurately. In particular, sensors such as gyroscopes, accelerometers and other mass-motion-measuring or other functions require more damping. An example is a gyro mounted in a housing filled with oil or other liquids. The hardest problem encountered is liquid viscosity. For example, the viscosity of silicone oil changes with ambient temperature. Any change in damping fluid viscosity will change the damping ratio, causing a measurement error output signal. This is the case, for example, when the angular velocity is input into the rate gyroscope. Previous techniques in this area, including temperature or damping compensation of a number of mechanical devices, is to reduce the impact of changes in the top of the gyro damping, damping force to get the value. However, in all of these systems, compensating for damping (ratio) changes due to temperature changes requires complicated and expensive mechanical devices. In contrast to the prior art, the present invention employs electronic circuitry to directly compensate for output signals proportional to temperature-induced damping variations, thereby substantially eliminating the previously used temperature or damping compensation mechanism.
