Delta算子系统的极限环问题分析

Limit Cycle Analysis of Delta Operator Systems

Delta算子数字控制器的实现和有限字长研究在高速采样情形下显得尤为重要。本文研究了高速采样时Delta算子系统极限环问题，利用Lyapunov方法给出Delta系统极限环的判别条件，并给出具体实现例子证明了结论的有效性。

Digital controller implementation and finite word length analysis using delta operator are very important in high speed sampling system. The limit cycles problems are considered in this paper, and new criteria for limit cycles in delta operator formulated systems with Lyapunov methods are presented. The result of an example proves the theoretical correctness
