1、设定位置环的前馈增益;

2、设定值越大时，表示在任何频率的指令脉冲下，位置滞后量越小;

3、位置环的前馈增益大，控制系统的高速响应特性提高，但会使系统的位置不稳定，容易产生振荡;

伺服系统主要作用

1、以小功率指令信号去控制大功率负载;

2、在没有机械连接的情况下，由输入轴控制位于远处的输出轴，实现远距同步传动;

3、使输出机械位移地跟踪电信号，如记录和指示仪表等。

1. Set the feedforward gain of the position loop;

2. The larger the set value, the smaller the position lag under any frequency instruction pulse;

3, the position loop feedforward gain is large, the high-speed response characteristics of the control system is improved, but the position of the system will be unstable, easy to produce oscillation;

Main function of servo system

1, with low power command signal to control high-power load;

2, in the case of no mechanical connection, the input shaft controls the output shaft located in the distance to achieve remote synchronous transmission;

3, so that the output mechanical displacement to track the electrical signal, such as recording and indicating instruments.
