| 摘 要： | 对球杆系统进行了机理建模,并针对球杆网络化控制系统网络负载小、节点少、带宽冗余等特点,从网络通信原理的角度分析了网络延时的不确定性,结合测试结果提出了具有时变性、分段保持性延时特征的网络环境的假设.在这个前提下,将网络分布时延转换为前向通道上的单一时延.在此基础上提出了球杆网络化控制系统的根据延时分段补偿控制的策略及在...

| Abstract: | The ball-beam system consists of a long beam which can be tilted by a servo or electric motor together with a ball rolling back and forth on top of the beam.It is a popular textbook example in control theory.The significance of the ball-beam system is that it is a simple system which is open-loop unstable.Even if the beam is restricted to be very nearly horizontal,without active feedback,it will swing to one side or the other,and the ball will roll off the end of the beam.To stabilize the ball,a control sys... |
