摘　　要：对于一种用于电机测试的全闭环三轴交流伺服驱动自动定位安装台架,在其x、y、z三轴传动系统中,我们以工况最严苛的z轴为对象,建立了该轴传动系统的动力学模型.运用Matlab/Simulink对z轴荷载运行时的动态特性进行了仿真分析,得到其电流环、速度环、位置环的阶跃响应特征,从而初步揭示了荷载因素对系统动态特性的影响规律,同时也验证了z轴控制结构及系统设计参数的基本合理性.另外分析了由荷载对z轴动态性能的影响而导致的运动位置偏差效应,并通过实验进行了验证.In this paper,the research work involve a kind of automatic positioning installation bench used for the motor test with closed loop three axis ac motor servo drive.Because the Z axis of the three shaft transmission system contained by this bench possess the most rigorous working condition,so we take the Z axis as an object,thus establish a dynamics model.Using the Matlab/Simulink,we complete the simulation analysis to dynamic characteristics of Z axis under the condition of load running,get the step response characteristics of the current loop,speed loop and position loop,thus preliminarily reveals the pattern about the load factor influence the dynamic characteristics of a system,and also to verify the basic rationality of Z axis control structure and system design parameters.In addition,we also analyze the movement position deviation effect caused by the fact that load influence dynamic performance of Z axis,and verify this effect by experiment.
