几种消除计算机干扰方法的效果的对比研究

在实际的计算机控制系统中,存在多种形式的干扰或扰动,这些干扰或扰动伴随着系统的动态响应而存在,使得被控对象不能很好地跟踪期望信号或平稳地工作在设定点上。为了得到期望的高精度控制效果,需要结合实际控制系统来分析研究不同干扰的来源及其消除方法。本文对一个计算机控制的直流电机随动系统中各种干扰做了分析并提出了几种消除方法,实际电机上的对比实验结果表明这些方法的有效性。

There are a lot of disturbances in actual computer control systems.These disturbances,tog ether with the dynamic response of control system,disturb the plant from tracking the reference sig nal or working steadily on the set point.In order to g et hig h precision control effect,it's need to investig ate and analyze sources and elimination techniques of the difference disturbance in actual control system.The paper analyzes some kinds of disturbance in a computer control DC servomotor system and proposes some elimination techniques.Comparison experiences on the actual DC servomotor system prove the validity of these techniques.
