1. automobile longitudinal acceleration tracking control method;

  • It is characterized in that;

    It is the estimator that utilizes the property the taken advantage of ambiguous model of the controlled device of being made up of the reverse of automobile and the positive power model element in gathering to design;

    Model error between each model and the practical object is estimated the system gain of current input signal, and with this system gain of estimating to obtain as switching target function, from the controller set that designs according to the element the said property the taken advantage of ambiguous model set, select corresponding controller online;

    The engine air throttle aperture is controlled, realized the tracking Control of automobile longitudinal acceleration;

    This method contains the following steps of in entire car controller, carrying out;

    1) initialization;

    The parameter of vehicle parameter and automobile running environment;

    δ

    ;

    the exponential decay coefficient, its scope is;

    0.1~

    1;

    U;

    Acceleration Control amount, its initial value are 0;

    With the corresponding estimator set of element in the set of the controlled device property taken advantage of ambiguous model be;
