伺服电机的三种控制方法
1、转矩控制:转矩控制方式是通过外部bai模拟量的输入或直接的地址的赋值来设定电机轴对外的输出转矩的大小。
2、位置控制:位置控制模式一般是通过外部输入的脉冲的频率来确定转动速度的大小,通过脉冲的个数来确定转动的角度,也有些伺服可以通过通讯方式直接对速度和位移进行赋值。
3、速度模式:通过模拟量的输入或脉冲的频率都可以进行转动速度的控制,在有上位控制装置的外环PID控制时速度模式也可以进行定位,但必须把电机的位置信号或直接负载的位置信号给上位反馈以做运算用。
位置模式也支持直接负载外环检测位置信号,此时的电机轴端的编码器只检测电机转速,位置信号就由直接的最终负载端的检测装置来提供了, 这样的优点在于可以减少中间传动过程中的误差,增加整个系统的定位精度。
