摘要
为削弱滑模控制的抖振现象,提出了一种基于汽车ABS滑移率控制的模糊滑模控制(FSMC)方法。该方法将模糊控制和滑模控制的优点有效地结合起来,利用模糊控制自适应调整滑模控制的趋近率参数,既保证了滑模控制的鲁棒性,又能够有效地削弱抖振,而且不依赖于精确的数学模型。将设计的模糊滑模控制器应用于单轮车辆模型及由Burck-hardt和Kiecheμ-S曲线所表示的轮胎模型,在MATLAB/Simulink6.5环境下进行仿真。结果表明,模糊滑模控制方法在ABS的滑移率控制中是切实有效的。
In order to weaken the chattering phenomenon of sliding mode control, a method of fuzzy sliding mode control （FSMC） based on the slip ratio control of automobile ABS was presented. This method hangs together the advantage of fuzzy control and sliding mode control, using fuzzy control to adjust the reach law parameter of sliding mode control. It ensures the robustness of sliding mode control, can weaken the chattering effectively, and it is independent of the accurate math modeL Applying the designed fuzzy sliding mode controller to the single wheel vehicle model and the tire model which was denoted by Burckhardt and Kieche μ-S curve, simulation was done in the MATLAB/Simulink6. 5 environment. The results show that the fuzzy sliding mode control method in the slip ratio control of ABS is valid.
