Abstract

In order to research the fatigue reliability of the vehicle drivetrian system,a new vehicle drivetrian road load simulation system is Designed to recreate the load spectrum on the indoor testbench. The band width of load simulation system was obtained according to the measured data.Based on iterative learning control(ILC),a sliding mode variable structure control(SMC) scheme was proposed for Road load Simulation System In order to improve the accuracy of load spectrum tracking. ILC generally improved the performance in the repetitive tasks by using the information from previous interations,and MSC which has the advantages of fasting respose and non-sensitive to the disturbance of the parameters was a good solution to the problem of robustness. Compared with the conventional PID control, the control precision of the control algorithm can be improved by 3.6%, the iterative load response error can be controlled within 5%, The target of indoor durability test is achieved.
