2、伺服系统稳定回路分析与设计‘贾建辉,赵书阳(北京遥测技术研究所·北京·100094)摘要:为提高方位俯仰型船栽天线伺服系统的船摇隔离度,稳定环是常采用的策略,但是选择传统的PID(ProportionalIntegralDerivative,比例积分微分)调节器往往不能获得满意的控制效果,针对该问题,提出了PID+积分+滞后校正环节作为稳定环调节器的具体实现形式。另外,通过对伺服系统内各环路带宽及响应速度的分析,将稳定环阶跃响应的上升时间作为参数调节依据。上述设计完成后,在实际系统中添加周期los,幅值8。的正弦波信号模拟船摇扰动,此时添加稳定环后,方位轴的船摇隔离度提
3、高了6dB,俯仰轴的船摇隔离度提高了13dB。这表明,采用PID+积分+滞后校正环节作为稳定环调节器的设计形式是正确且简单有效的。关键词:稳定环调节器;比例积分微分(PID)+积分+滞后校正;船摇隔离度;船载天线伺服系统中图分类号:V556;TN820.3文献标志码:A文章编号:1674—5620(2017)02一0101一05D()I:10.7642/j.issn.16745620.2017一02一0101一05AnalysisandDesignofaStabilizationLoopforShip—BorneAntennaSerVoSystemsJIAJianhui
