本文介绍的定位随动系统,是采用电流—速度—位置三环结构的数字模拟混合系统,用于板材横切线定尺长度的精确控制。本文对该系统的原理和性能作了简要介绍,并利用线性控制理论和工程设计方法着重讨论了系统动态参数的选择。
This article describes the positioning servo system, the use of current - speed - location of the three-ring structure of the digital simulation hybrid system for the precise control of the length of the cross-cut sheet length. In this paper, the principle and performance of the system are briefly introduced. The choice of system dynamic parameters is mainly discussed by using linear control theory and engineering design method.
