摘要
文章针对强非线性复杂时变的电子节气门,提出了一种基于自组织模糊规则的控制器。文章结合误差相平面分析了控制器的一般性能,以判别式进行规则修改决策,并得出控制量增量,以此直接修改模糊控制规则表中对应元素,从而建立自组织模糊控制系统。控制器适应性好,结构简单,鲁棒性强。仿真实验表明其实际效果良好。
In this paper, a novel self-organizing fuzzy control method for complex nonlinear time-vary ing electronic throttle is proposed. This paper analyzes controller＇s performance according to error phase plane as well as estimation of rules modification. So the variety of control is educed, and it brings the direct modification of rules table. This system can perfect fuzzy rules to achieve well performance even without accurately modeling the generators. Simulations illustrate the good performance for electronic throttle. This kind of fuzzy controller has strong robustness, well adaptability and it is simple.
