测试捷联—数字式姿态控制系统频率(动态)特性通常是把动力调谐陀螺置于高精度、宽频带角振动台上进行。本文提出一种在动力调谐陀螺伺服回路的校正网络输入端加电激励信号代替角振动台来测试姿态控制系统频率特性的方法。原理上讲,这种方法和用角振动台的方法是完全等效的,但由于取消了高精度、宽频带的角振动台,从而简化了测试设备,降低了测试设备的成本。
Test Strap - Digital Attitude Control System The frequency (dynamics) feature is usually done by placing a power-tuned gyroscope on a high precision, wide-angle angular vibration stage. In this paper, a method to test the frequency characteristics of attitude control system by replacing the angular vibration table with an electrical excitation signal at the input of the calibration network of the power tuned gyro servo loop is proposed. In principle, this method is completely equivalent to the method of vibrating a table with a corner, but simplifies the testing apparatus and reduces the cost of the testing apparatus by eliminating the high-precision wide-band angle vibrating table.
