N模冗余控制系统中,通道间非同步与各通道完全同步的系统具有不同的数据关系和对外控制作用。非同步系统可分为两类:各通道运行在相同频率上的系统和各通道运行在不同频率上的系统。文章讨论了这两类非同步系统与同步系统的差异,在此基础上通过试验分析了异步度对这两类系统的任务关系以及闭环控制特性等的影响,最后对该类系统的分析工具提出了建议。
N-module redundancy control system, the channel is not synchronized with the channel completely synchronized system has a different data relationship and external control. Asynchronous systems fall into two categories: systems that operate on the same frequency for each channel, and systems that operate on different frequencies for each channel. The paper discusses the differences between these two types of asynchronous systems and synchronous systems. Based on the analysis, the influence of asynchronous degree on the task relationship and the closed-loop control characteristics of the two systems is analyzed. Finally, the analytical tools of such systems are proposed Suggestion
