摘要：

液压油粘度的变化会对液压可变气门系统（VVA）性能产生重要影响，为提高内燃机的性能，
应根据发动机的运行工况调整最佳的气门正时及升程。该文建立了全可变气门机构的AMESim 仿真
模型，分析了液压油粘度对气门升程的影响。基于能量守恒定律建立了系统平均模型，利用Matlab/
Simulink 设计了滑模控制器。仿真结果表明：所设计的滑模控制器通过调节液压泵的转速，调节气
门升程，使气门工作精度提高了9.3%左右。因此，该控制器降低了液压油粘度变化带来的扰动影响。

Abstract:

Hydraulic oil viscosity has significant influence on the performance of hydraulic variable valve
actuation (VVA) systems. The optimal valve timing and lift should be quickly reached under any operating
condition to improve the efficiency of internal combustion engines. A mathematical model was built for an
electro-hydraulic VVA using AMESim software and then validated to study the influence of hydraulic oil viscosity
on the VVA performances. An average model of the VVA was developed based on the energy conservation
concept. A sliding mode controller (SMC) was designed by using the average model in Matlab/Simulink. The
simulation results show that the proposed SMC can adapt the valve lift by adjusting hydraulic pump speed. The
SMC controller can improve the working aceuracy by 9.3%. Therefore, this SMC can eliminate the disturbances
caused by the variation of hydraulic oil viscosity.
