随动系统校正网络的设计

Design of Corrector in Servo System

由被控对象传递函数,可直接进行随动系统校正网络设计。首先,根据被控对象传递函数和灵敏度分析,简化被控对象逆模型。然后,由滤波器传递函数和滤波时间常数,直接求得校正网络的传递函数。通过某飞行仿真器上的实际应用例子,验证了该方法的可行性和实用性。

The corrector of servo system can be designed based on the transfer function of controlled object. Firstly, according to analyzing both the transfer function of the object and the sensitivity, the inverse model of the object is simplified. And then, according to the transfer function of filter and the filtering time constant, the transfer function of corrector can be calculated. The application of the corrector proposed in a flying simulator shows its validity.
