摘要
大多数故障诊断系统不能适应环境的变化,即不具备自适应性。针对这种情况,论文提出了故障诊断自适应策略,该自适应策略由状态空间和策略空间构成,状态空间用来描述环境状态,策略空间用来描述采用的策略。对于状态空间中的某一具体的环境状态,在策略空间存在唯一的策略与之对应。实验结果表明,论文提出的故障诊断自适应策略是比较有效的。
Most fault diagnosis system could not adapt the variation of environment. Aiming at this problem, this paper proposed an adaptive fault diagnosis strategy which composed of state space and strategy space. The former described environment state and the latter described the strategy. There was an exclusive strategy corresponds to a certain environment state in state space. The experiments indicate that the adaotive strategy of fault diagnosis is effective.
