为提高动中通伺服系统的通用性,设计了一种具有系统辨识功能的动中通伺服系统。着重研究了伺服系统辨识时的输入信号需满足的条件,通过理论推导,获得了基于最小二乘法输入信号为阶跃信号时必须满足的限定条件。以符合该限定条件的阶跃信号作为输入对伺服系统进行辨识,得到了能够较好的反映卫星动中通伺服系统特性的数学模型,验证了利用满足该条件的阶跃信号作为输入对卫星动中通伺服系统辨识的可行性。

In order to improve the versatility of Servo Systems in SOTM, a Servo Systems in SOTM with system identification function was designed. Focusing on the conditions that the input signal needs to meet when the servo system is identified, Through theoretical derivation, the necessary conditions that must be satisfied when the input signal is a step signal based on the least squares method are obtained. The servo system is identified by taking the step signal that meets the defined condition as input, and a mathematical model that can better reflect the characteristics of the Servo Systems in SOTM is obtained. The feasibility of using the step signal satisfying this condition as an input to identify the servo system in SOTM is verified.
