摘要

绝对死带采样在离散控制系统中用于减少产生事件的数量。在适当的条件下，这种采样方式会在稳态下产生极限环，导致事件数增加，降低采样效率。本文研究了PI控制器闭环中极限环出现的条件，以及极限环出现的频率。

Limit cycles in PI control loops with absolute deadband sampling

Absolute deadband sampling is used in discrete control systems for reduction of the number of produced events. Under proper conditions, this sampling type results in limit cycles in steady state, which lead to increased number of events and deteriorate the sampling efficiency. This paper investigates the condition of emergence of limit cycles in the closed control loops with PI controllers, as well as the frequency of limit cycles.
