在自动控制系统中,能使输出量以一定准确度跟随输入量的变化而变化的系统称为伺服系统.在伺服系统中要使系统有良好的跟踪性能,运动轨迹命令的设计尤为重要.首先介绍了伺服系统中常用的3种运动轨迹命令;介绍了传统的S型运动轨迹命令的设计方法;最后在实际的伺服系统上进行了实验研究,并给出了实验结果.
In automatic control system,the system whose output follows with the input with certain accuracy is called servo system.The motion profile design is very important to make the servo system have a good following performance.Firstly,three popular motion profiles used in servo system are presented.Secondly,the design method of S curve motion profile is presented.Finally,the experiments have been done on the servo system and the experiment results are given.
