【摘要】：为实现龙门双轴运动的同步,提出采用时域响应分析方法,从同步运动系统的各轴伺服响应差异入手分析同步误差的产生原因,分别推导出位置斜坡和位置正弦参考命令下龙门双轴同步误差的理论计算公式,得到两轴伺服增益系数、积分时间常数及参考命令参数与同步误差的定量关系。由MATLAB/Simulink建模仿真分析可知:在各参考输入下推导的同步误差理论计算公式正确;获得两轴伺服增益系数对同步误差的影响关系,即减小两轴伺服增益不匹配程度、增大两轴伺服增益系数能抑制同步误差。
[Abstract]:In order to realize the synchronization of the gantry biaxial motion, a time-domain response analysis method is proposed to analyze the causes of the synchronization error from the differences of the servo responses of the synchronous motion system.The theoretical calculation formulas for the biaxial synchronization error of the gantry under the position slope and the position sinusoidal reference command are derived respectively. The quantitative relationship among the two-axis servo gain coefficient, the integral time constant and the reference command parameters and the synchronization error is obtained.The results of MATLAB/Simulink modeling and simulation show that the theoretical formula of synchronization error derived from each reference input is correct, and the influence of two-axis servo gain coefficient on synchronization error is obtained, that is, to reduce the mismatch degree of two-axis servo gain.The synchronization error can be reduced by increasing the gain coefficient of two axis servo.
