基于模糊逻辑的自动离合器控制策略设计与仿真

摘要

The electro-mechanical continuously variable transmissions (EM-CVT) represent an area of great industrial interest that is obtained much of the attention all over the world.The automatic clutch control is a core technology for the development of EM-CVT.The paper presents a new control strategy to the automatic clutch of an EM-CVT using the rules of fuzzy logic.The clutch system modeling was constructed including clutch mechanism model,clutch transmission model,and intemal combustion engine model.MATLAB/Simulink simulation is performed to validate the fuzzy logic control performance of the automatic clutch under different operating modes,comprising starting up on flat and hill-start roads.The proposed approach develops a reasonable reference for design the automatic clutch of the EM-CVT.%介绍了一种基于模糊逻辑的EM-CVT自动离合器控制策略.建立了离合器机械模型、离合器传动模型以及内燃机模型.使用MATLAB/Simulink仿真验证了在不同工况下自动离合器的模糊逻辑控制性能,包括平路起步、坡道起步等工况.提出的方法为EM-CVT自动离合器的设计提供了参考.
