STUDY OF QUADRATIC COST FUNCTIONS FOR VEHICLE HEADWAY CONTROL

This paper shows that minimizing a quadratic cost function is not particularly useful for selecting a small number of controller gains in vehicle headway control. For cases in which a large number of controller gains are to be selected, the quadratic cost function may be useful, but the weighting parameter values cannot usually be chosen a prior if transient performance measures are of particular interest. Examples illustrate how values of weights in a simplified cost function can be selected to yield acceptable transient performance. This performance is compared with that for a system containing only a few gains and optimized without recourse to a cost function. /Author/
