摘要: 根据Schank的动态记忆理论,研究了信息系统的分类,给出了具有智能性质的决策算法。动态系统的故障检测可归结为系统有故障和无故障,由此给出了故障检测的智能决策算法。许多复杂的故障检测算法可归结为简捷的线性函数正、负的判断,因而可有效降低算法的复杂性。实例验证了故障检测的智能决策算法的有效性。

Abstract: According to Schank's dynamic memory theory- the classification of information system is studied, and the decision algorithm of intelligence is given. The failure detection of dynamical system can be considered as the classification between the subset with failure and the subset without failure. So the intelligent decision algorithm for failure detection is derived. By the algorithm, many complicated failure detection algorithm can be simplified as linear functions, and thus ti is a convenient algorithm. In addition, the algorithm releases the strict requirement on the statistical properties of the system, and therefore it has a good robust properly. An example is also given to prove the effectiveness of the algorithm.
