多输入多输出网络控制系统时延同步研究

Research on Delay Synchronization in MIMO Networked Control Systems

针对单输入单输出和多输入多输出网络控制系统中存在的时延抖动和时延偏移问题,提出了在控制器和执行器前设置缓冲区的方法。通过设置缓冲区.可以减小时延抖动和时延偏移,使之限制在一个合理的范围内,从而减小其对网络控制系统性能的影响,使系统保持稳定.达到时延同步的目的。仿真示例验证了该方法的有效性。

For the problems of delay jitter and delay skew consisting in SISO and MIMO networked control systems, the method of setting buffers before controller and action is bring forward.By setting buffers,delay jitter and delay skew can be reduced to a reasonable bound,which allay the effect to networked control systems performance and make systems stability,so achieving delay synchronization purpose.The example illustrates the validity of this method.
