摘　　要：阀控马达系统是雷达转台伺服系统的重要组成部分,其中电液伺服阀是高性能阀控马达系统的主要控制元件。电液伺服阀涉及机械、电子、磁场、流场等多学科领域,其数学模型较为复杂,传统的阀控马达系统模型缺乏对电液伺服阀的精确建模,因此极大地限制了电液伺服阀的结构设计和迭代优化。为满足某型雷达转台阀控马达系统高精度、高动态特性的要求,以阀控马达系统为研究对象,建立了包含电液伺服阀关键参数的阀控马达系统精细化数学模型。基于MATLAB/Simulink仿真软件对所建立的系统数学模型进行动态特性仿真和频率响应分析,为改善系统的动态精度和稳定性,优化电液伺服阀的结构参数提供理论支撑和仿真参考。The valve controlled motor system plays an significant role in the servo control system of radar turntable,and the electro-hydraulic servo valve is the main control element of high performance valve-controlled motor system.Electro-hydraulic servo valve involves mechanical,electronic,magnetic field,flow field and other multidisciplinary fields,and its mathematical model is more complex.The lack of precise mathematical modeling for electro-hydraulic servo valve in traditional valve-controlled motor system greatly limits the structural design and optimization of electro-hydraulic servo valve.In order to meet the requirements of high precision and high dynamic characteristics of a radar turntable valve-controlled motor system,this paper takes valve-controlled motor system as the research object,and establishes a detailed mathematical model of valve-controlled motor system including key parameters of electro-hydraulic servo valve.Based on MATLAB/Simulink simulation,dynamic characteristic simulation and frequency response analysis of the established system mathematical model are carried out.The research results provide theoretical support and simulation reference for improving the dynamic accuracy of the system and optimizing the structural parameters of the electro-hydraulic servo valve.
