现在,市场上已经有小功率,低成本的陶瓷压电速率陀螺仪。但是,这些陀螺仪用到的石英晶体的低温特性甚差。不过,我们可用一台伺服放大器来消除与温度有关的漂移造成的直流电平偏移(如图1所示)。使用这种小型、坚固的陀螺仪的本来想法,是为了把视频摄录机(video-camcorder)的抖动阻尼掉。不过,这 There are already low-power, low-cost ceramic piezo rate gyros on the market. However, the quartz crystals used by these gyroscopes have poor low-temperature characteristics. However, we can use a servo amplifier to eliminate temperature-dependent drift caused by the DC level offset (Figure 1). The original idea of ​​using this small, rugged gyro was to dampen the jitter of the video-camcorder. However, this
