Abstract
A model-based control system for controlling a state of an operating subject such as an engine, characterized by forming an inverse model using a forward model and a feedback control system. The subject is modeled using first-order lag elements and dead time, and dead time is removed from the feedback control system. Responsiveness is high not only during a stable state but also during a transient state.
