摘　　要：提出了一种新的过程控制故障诊断规则的增量动态更新方法。根据给定的过程控制故障规则的描述,按照规则更新集与控制状态集在约束条件作用下,将规则更新问题归结为一类标准形式,并给出问题的形式化描述;然后以理论修正算法为依据,利用提出的知识更新算法对问题求解以完成知识库的规则更新。最后,给出的仿真实例验证了该方法的有效性和可行性。A new dynamic updating incremental rules method based on rough set theory for fault diagnosis of process control is approach.According to the description of rules of fault diagnosis of control process, in terms of a set of updating rules and a set of control station under constraints,the problem of updating rules is boiled down to a kind of standard format,and the formalization is given.Then,based on the theory revision methods,the proposed method is used to fulfill updating rules of knowledge base.The simulation results show that the method is valid and feasible.
