Investigation on adaptation for speed control system of gasoline engine using the design method of servo system to attain the given settling time

Abstract

In order to satisfy the setting settling time and overshoot, a new design method of controller was developed using a model parameter which was approximated as a second-order lag-time system. Then, an effectiveness was experimentally demonstrated as an engine speed controller. In order to operate wide conditions, however, an adaptive ability was required for parameter change. This paper investigated regarding an on-line execution of non-linear least square problem to obtain the changed controlled plant model parameter. A simulation study were carried out and a suitable adaption were experimentally demonstrated.
