摘要
在伺服控制系统中,幅频特性通常容易实现,相频特性经常难以达到要求。相频特性反映了伺服系统对输入信号的跟随性,其特性往往决定着系统的整体性能。对某型无人直升机数字舵回路中影响相频特性的关键环节进行分析,并就如何提升舵系统的相频特性提供了方法。
In the servo control system, the amplitude frequency characteristics are usually easy to achiever the requirement than phase frequency characteristics. Phase frequency characteristics reflect the servo system to follow the input signal,and its characteristic is often determines the overall performance of the system. This article analyzes the phase frequency characteristic of an unmanned helicopter’ s rudder system,and bring forward a method to optimize the capability of rudder system.
