Abstract This paper presents a hybrid fuzzy controller structure to improve ride comfort-road holding trade-off characteristics of a full vehicle active suspension system. The controller includes two interval type-2 fuzzy logic controllers, optimized for ride comfort and road holding, for each tire. Type C random road profiles according to ISO 8608 are applied to each tire in the model and ride index, road holding, crest factor, and RMS acceleration values are evaluated. Stability of the overall closed loop system is presented by phase plane analysis. The simulation results reveal that simultaneous improvement of ride index and road holding can be made possible with the proposed controller.

基于区间2型模糊控制的整车主动悬架系统乘坐舒适性-道路保持权衡改进

摘要 本文提出了一种混合模糊控制器结构,以改善整车主动悬架系统的平顺性-道路保持权衡特性。该控制器包括两个区间 2 型模糊逻辑控制器,针对每个轮胎的乘坐舒适性和道路保持性进行了优化。根据 ISO 8608 的 C 型随机道路剖面应用于模型中的每个轮胎,并评估行驶指数、道路保持力、波峰因数和 RMS 加速度值。整个闭环系统的稳定性通过相平面分析来呈现。仿真结果表明,所提出的控制器可以同时提高行驶指数和道路保持力。
