測者子圈
英文
lower branch of the observer's meridian-
The bias magnetic field of the bias coil driven by bias current and small signal test current, results in the induced signal of the control coil. the terminal voltage of the control coil is detected by the test circuit. then the signal containing the information of rotor displacement is obtained, from which we can get the dc voltage signal proportional to the rotor displacement through half - wave rectification circuit and low pass circuit. this dc signal is put into a pid controller to get the control signal of the rotor displacement
偏置測試電路向偏置線圈輸入偏置電流和小信號測試電流,兩者產生的偏置磁場在控制線圈產生感應信號,檢測電路檢測控制線圈端電壓並提取含有轉子位移信息的電壓信號,該信號經半波整流電路和低通濾波電路后得到與轉子位移成正比例的直流信號,再由pid控制器轉換為轉子位移的控制信號,最後控制信號輸入功放電路產生控制電流,實現閉環控制。A celestial object will reach its highest position when passing through the semi - circle which includes the zenith and the nearest celestial pole, and this phenomenon is called upper culmination
