Quadratic optimal control improves the over-all performance of launch control of AMT(automated manual transmission),however the control performance cannot be guaranteed,or even fail to start-up the vehicle successfully,when the clutch friction coefficient,vehicle mass and road slope angle vary to some large extent.A linear quadratic output regulator with disturbance/modeling error observer is then proposed to provide consistent optimal performance.The control law is derived as a linear feedback form of the system states and the estimated modeling errors/disturbances,and the system output is guaranteed to be asymptotically stable,which will significantly relax the dependence of the controller on modeling accuracy,and extend the application of LQR theory.Finally,the proposed control law is tested through simulation of a mid-size passenger car(BESTURN B50 of FAW,China).
