本文探讨了模糊控制器设计的直接试探法,提出了以性能模型为参考的设计方法。 在总结极大极小合成方法的基础上,给出了用逻辑电路实现模糊算法和精调控制器提高系统性能的方法;针对极大极小方法中信息量不足的缺陷,提出了用模糊数和插值原理设计控制器的方法。 把性能指标转换成性能模型,用模糊集理论测辨对象的模糊数模型,用计算机实现模糊算法,构成以性能模型为参考的设计方法。
This paper discusses the direct heuristic method of fuzzy controller design, and puts forward the design method based on the performance model. On the basis of summing up the minimax method, this paper presents a method of using the logic circuit to realize the fuzzy algorithm and the fine tuning controller to improve the system performance. In view of the shortcomings of insufficient information in the minimax method, And interpolation principle design method of the controller. The performance index is converted into a performance model, the fuzzy number theory is used to identify the fuzzy number model of the object, and the fuzzy algorithm is implemented by the computer to form a design method based on the performance model.
