<p>PURPOSE: To most suitably control the charging of an internal combustion engine and further to restrain the installation cost as possible. CONSTITUTION: A system includes charging devices 106, 114, 116 of an internal combustion engine, actuators 122, 124 for regulating the charging, means 134 for forming a control deviation (e) that characterize the charging such as pressure, air volume, air quality, etc., a controller 136 for evaluating operation quantity that drives the actuator from the control deviation, and means 130 for detecting rotational speed of the internal combustion engine. In order to optimize a closed loop control, the transmission characteristics of the controller 136 are regulated by the rotational number (n) of the internal combustion engine, and the operating parameter (g) which characterizes the output dynamics of the internal combustion engine and the charging devices. In the case of large control deviations, the operating parameter (g) is derived from the actual value (y) of the controlled variable. In the case of small control deviations, a steady- state operating condition is considered, and an empirical value is used for the operating parameter (g).</p> |
