本文提出了一类异步多速率采样控制系统 .针对这类非周期异步多速率系统分析、设计困难这一问题 ,研究了其闭环系统性能关于采样器、保持器时间延迟的连续性问题 .结果表明 ,其闭环系统性能是采样器、保持器时间延迟的连续函数 .据此连续性 ,在少许改变系统性能的前提下 ,可以以任意给定精度将非周期异步多速率系统转变成周期异步多速率系统 ,再应用已有方法对其进行处理 .
This paper presents a class of asynchronous multi-rate sampling control system.Aiming at the problem of such aperiodic asynchronous multi-rate system analysis and design difficulties, the continuity of the performance of the closed-loop system with respect to sampler and retainer time delay is studied. , Whose closed-loop system performance is a continuous function of the time delay of the sampler and the keeper.According to this continuity, under the premise of slight change of system performance, the non-periodic asynchronous multi-rate system can be transformed into periodic asynchronous multi-rate System, and then apply the existing methods to deal with it.
