| 摘 要： | 针对非最小相位系统具有右半平面零点,使系统阶跃响应存在负调,以及常规方法控制不理想等问题,在分析常规模糊控制器的基础上,提出了一种新型的模糊积分控制器的设计方法,改善了常规模糊控制器的动态和稳态性能。对输入变量设计了一种简单可调整宽度的三角形隶属度函数;并针对非最小相位系统,提出了一般情况下控制规则基的设计原则。计算机仿真结果证实了这种设计方法的有效性。

| Abstract: | For zeros in the right-half plane of non-minimum phase systems, they can cause undershoot in the step response of systems, and the regular control methods are not prefect . So a novel fuzzy-integrate controller based on the analysis of the regular fuzzy controller was proposed. It improved the dynamic and static capability of the regular fuzzy controller. For the input variables designed a simple and variable-span triangular membership function. The design principles of the control rule base under common conditions for non-minimum phase systems is proposed. The computer simulation result have turned out the feasibility of this controller. |
