在多时延影响下,网络控制系统的控制效果将有所下降,甚至可能不稳定。针对这种情况,文章对系统输出误差变化与多个时延之间的关系进行了“量化”描述,并建立了两者之间的函数关系式Φ,通过Φ反映了多时延对系统性能的影响。文章最后通过实例仿真验证了该函数关系式的有效性。 Under the influence of multi-delay, the control effect of the network control system will decline, and may even be unstable. In view of this situation, the paper describes the relationship between the system output error variation and multiple delays by “quantification” and establishes the functional relationship Φ between them, which reflects the effect of multiple delays on system performance influences. Finally, the article verifies the validity of the functional relation by the example simulation.
