摘要
通过对柴油发电机组有功功率和频率变化特性的分析表明,采用常规控制方法解决非线性、非实时性数学模型存在一些问题,本文提出了一种基于模糊数学的算法──模糊控制,采用语言变量来描述系统,可得到一套控制规则,能很好地解决频载调节过程中频率和有功功率的耦合问题。文中给出了一个具体的FUZZY控制器的设计方案。
Having the feature of nonlinear,changing with time and time delay in the synchronous system,it is difficult to regulate the frequence and loads of power unit with PID algorism for such generators that have a complicate mathematical model.A new method which uses FUZZY logic is presented in this paper.According to the knowledge of the workers to the system,FUZZY control rules are suggested.Because FUZZY control rules do not need the precise mathematical model,a good result can be achieved.The design of FUZZY set for refulation in power unit is given in detail.
