摘要
将多体系统动力学与智能控制理论相结合对汽车制动防抱死控制系统进行了研究,利用ADAMS/CAR建立了汽车整车的多体力学模型,模型包含了前后悬架、动力总成、转向系统、稳定杆、制动系、轮胎力学模型以及车身,同时也考虑了轮胎、衬套、弹簧、减震器等部件的非线性,准确地表达了车辆的动态特性;利用Matlab/Simulink模糊控制工具箱建立了制动防抱死控制系统的模糊控制策略,利用ADAMS/Control接口进行模型的集成、协同仿真,并将仿真结果与另一种控制策略-逻辑门限值控制的仿真结果进行了比较和分析,仿真反映出模糊控制在整车制动防抱死控制系统上的应用效果,结果表明该控制算法稳定好并具有较强的鲁棒性。
The research of anti-lock braking system based on multi-body system dynamics and intelligent control theory are presented. A multi-body vehicle dynamic model is built by ADAMS/CAR.The model includes front and rear suspension system, engine system, steering system, antiroll system, brake system, the model of tire dynamics and vehicle body.It also considers the nonlinear characteristics of the tire, bushing, spring and damper and can accurately express the dynamics performance of the vehicle. In addition, a fuzzy control model of ABS was built by Matlab/Simulink, and the two model are integrated and co-simulated by the interface of AD- AMS/Control.The results of simulation is compared with the results of another control method-logic limit values control.The analysis resuits show that fuzzy control has better effects on vehicle ABS and it has more better stability and robustness.
