摘　　要：基于Matlab/Simulink建立了装备金属带式CVT的车辆传动系统仿真模型,设计并通过试验优化了速比控制器及夹紧力控制器的模糊控制策略,并与采用常规PID控制的控制器进行了对比仿真试验。仿真结果表明,模糊控制是解决复杂系统控制问题的理想途径,经过优化的模糊控制策略应用于金属带式CVT具有较好的控制效果。A simulation model of vehicle drivetrain system with metal belt CVT is built on software Matlab/ Simulink,and the fuzzy logic control strategy for ratio controller as well as clamping force controller is designed ＆ optimized,and compared with normal PID controller.The simulation results show that fuzzy logic control is the best solution to complicated system control,and the optimized fuzzy logic control strategy has good control effects in application to metal belt CVT.
