雷达导引头天线液压控制

Hydraulic Control System of Antenna for the Radar Seeker

设计导引头天线液压控制的关键是确认液压伺服机构的特性,通过理论分析、试验校正等方法可提高模型的有效性。分析了伺服阀控制的液压机构特性,用古典控制理论设计了一种雷达导引头天线液压伺服系统,讨论了预定精度分配、稳定回路去耦性能设计、改善系统低速平稳性等问题,仿真结果表明设计方法有效。导引头液压控制设计的基本方法,可应用于其它形式的伺服系统中。

<Abstrcat>The identified model of the hydraulic servomechanism is the key of the design, it can improve the validity of the model by the analysis with the theory and the amendment with the examination. Analyses hydraulic mechanism characteristics of servo valve control, and designes the hydraulic servo system of antenna for the radar seeker with the classical control theory. The precision of the destine loop, the decoupling performance of the stabilization loop and the calm motion in low speed are brought and solved. The simulated data prove the availability of design method. The function, the method and the measurement in this paper may be applied to other servo systems.
