摘　　要：提出一种基于牛顿在线插值算法的模糊控制器,介绍该控制器的设计方法。该方法既简化了合成推理运算,又能满足模糊控制规则的完整性要求,从本质上消除由于量化误差和调节死区给模糊控制系统带来的稳态误差与颤振现象。通过仿真证明系统的性能得到明显改善。This paper presents an on-line Newton interpolation algorithm in the fuzzy control system and introduces the designing method of the controller. The method not only simplifies the complexity of composite reasoning, but also meets the request on the integrality of control rules. Moreover, it can improve the stable performance of the controller and eliminate essentially the stable oscillation caused by the scaling error and dead area. The comparison of simulation shows that the method has good control performances.
