Abstract

See full text

A dynamic feedforward amount to realize a predetermined transient response characteristic by compensating a transient response characteristic of an engine having a Variable Nozzle Turbo (VNT) and an Exhaust Gas Recirculator (EGR) is calculated for a nozzle opening degree of the VNT and a valve opening degree of the EGR. The transient response characteristic of the engine responds to a setting value of an injection quantity or the like. Then, command values of the nozzle opening degree of the VNT and the valve opening degree of the EGR are calculated by using the dynamic feedforward amount. In the transient state, the followingness to the target value is improved.
