摘　　要：针对具体的仿真转台电液位置伺服系统,着重分析了液压马达摩擦非线性、框架间动力学耦合、反馈测量元件的分辨率误差和安装误差对转台电液位置伺服系统精度的影响。通过实验和仿真可以看出,摩擦阻碍了转台电液位置伺服系统商精度控制的实现, 任何一个框架的运动都会对其余框架的伺服驱动系统产生干扰力矩并引起伺服系统误差,反馈测量元件的分辨率误差和安装误差直接反映在伺服系统输出上,对伺服系统的精度有直接影响。Emphasis is placed on analyzing the influences of friction characteristics on hydraulic motor, dynamic coupling between gimbals, resolution ratio error and setting error of feedback measurement element on accuracy of electro-hydraulic position servo system for a certain simulation turntable. From the experiment and analysis, it can be seen that friction limits realization of high accuracy electro-hydraulic position servo system, movement of any gimbal brings disturbance moment to servo system of other gimbals and the disturbance moment causes error, and, resolution ratio error and setting error of feedback output. measurement element are directly added to servo system
