摘要
可达性问题的研究是众多领域迫切希望解决的问题之一 .比如一个计划能不能实现 ,一个问题能不能解决 ,这些都属可达性问题 .本文主要从控制论的角度研究可达性 .传统的模糊控制器 ,由于其输入被量化环节离散分档后 ,其输出本质上是抖动的 ,因而被控量存在稳态误差 ,或在工作附近存在一定幅度的振荡 ,这就充分体现了其过程存在“动态性”和“模糊性”问题 .因此 ,本文基于动态模糊理论 ,针对模糊控制器的不足 ,对具有动态模糊性的问题作进一步的研究 ,给出动态模糊目标可达性基本理论 ,其内容包括 :DF目标表现可达性定理 ,DF目标分解可达性定理 。
The research of accessibility problem is a key problem to must be carefully studied and tackled on much domain. E·g ,realiZe a plan is both can and can't, problem to solve is both can and can't, these question belong to accessibility problem. In traditional fuzzy control machine, after input is dispersed shelves of quantitative changed link, that outputself is vibratile, so controled quantative exists state of firm error, or to varying degrees exist vibration in work nearby, the fully embodies character of dynamic and fuzzy is existed in the control process. Consequently, this paper based on the dynamic fuzzy theory, to counter weaknesses of fuzzy control machine, with character of dynamic and fuzzy go a step further research, the dynamic fuzzy objective accessibility theory is proposed, contents of them are accessibility theorem of representation and decomposition and extension of dynamic fuzzy objective, and so on.
