在实际的伺服控制系统中,上述的每个环节在硬件特征上并不独立,可能几个环节在一个硬件中,如测速直流电机即是执行元件又是检测元件。伺服驱动系统的分类数控机床的伺服驱动系统按其用途和功能分为进给驱动系统和主轴驱动系统;按其控制原理和有无位置检测反馈环节分为开环系统和闭环系统;按驱动执行元件的动作原理分为电液伺服驱动系统和电气伺服驱动系统。电气伺服驱动系统又分为直流伺服驱动系统和交流伺服驱动系统。
1.进给驱动与主轴驱动进给驱动是用于数控机床工作台或刀架坐标的控制系统,控制机床各坐标轴的切削进给运动,并提供切削过程所需的转矩。主轴驱动控制机床主轴的旋转运动,为机床主轴提供驱动功率和所需的切削力。一般地,对于进给驱动系统,主要关心它的转矩大小、调节范围的大小和调节精度的高低,以及动态响应速度的快慢。对于主轴驱动系统,主要关心其是否具有足够的功率、宽的恒功率调节范围及速度调节范围。
2.开环控制和闭环控制数控机床伺服驱动系统按有无位置反馈分两种基本的控制结构,即开环控制和闭环控制。由此形成位置开环控制系统和位置闭环控制系统。闭环控制系统又可根据位置检测装置在机床上安装的位置不同,进一步分为半闭环伺服驱动控制系统和全闭环伺服驱动控制系统。若位置检测装置安装在机床的工作台上,构成的伺服驱动控制系统为全闭环控制系统;若位置检测装置安装在机床丝杠上,构成的伺服驱动控制系统则为半闭环控制系统。现代数控机床的伺服驱动多采用闭环控制系统。开环控制系统常用于经济型数控或老设备的改造。
