Abstract:Start- up working condition is the key to the research of optimal engagementof automatic clutch for AMT.The engagement quality is mainly influenced by throttle angle,engine state,gear ratio and load.The enginestate ismonitored by nonlinearmethod cooperated with model reference adaptive control, which avoids flameoutorfly- off.Since weariscontradicted with smooth running,a tradeoff optimal objec- tive function wassetup and an optimal processcontrol was carried outon the basisof minimum theory.By use of the explicitexpression involving the main facts,the accurate control and furtheranalysis penetrating into the dynamicessence were developed.On the comparison of the engagementquality of differentdriving modes by means of the test and simulation,it is shown that the adaptive optimal control is effective and feasible.
Keywords:automatic clutch  nonlinear control  adaptive control  optimal control
