摘　　要：自动离合器的接合过程存在冲击度大和摩擦片磨损严重的问题。为了改善冲击和滑摩,提出参考模型自适应控制(MRAC)思路,基于波波夫超稳定理论求解,动态控制滑摩扭矩,使得滑摩过程的动力学状态尽快逼近同步模型的动力学状态。在SimulationX环境中建立仿真模型,仿真结果表明,MRAC控制既减少滑摩功,又消除同步点冲击,明显提高接合品质,是一种不牺牲滑摩功却能改善平顺性的新方法。Intensive jerk of transmission components and excessive wear of frictional plate are still serious during engagement of automated clutch. In order to improve the performance concerning jerk and wear, a Model Referenced Adaptive Control （MRAC） was proposed to control frictional torque which could make the slipping dynamics approaching the synchronizing dynamics. The controller was resolved based on Popov hyperstability theorem. Both fast and slow start-up cases were simulated based on Simulation X software platform. The results show that the MRAC can not only reduce wear remarkably but also eliminate sudden jerk at the synchronized point. Unlike the conventional control methods, the MRAC can improve driving smoothness without sacrificing service life of clutch.
