An engine control education system is designed. This system can realize the following functions: it serves to familiarize people with gasoline engine properties and can be applied to carry out engine control simulation, to design engine control logic and to realize engine real-time simulation. In the paper, the structure of this education system is explained. The system is composed of a computer, a high-speed arithmetic processing board, an ECU and an engine test bench. Engine control simulations are carried out, and engine properties are obtained. Therefore this system can assist people in mastering gasoline engine properties. Besides, a real-time simulation system is designed, and PID control real-time simulation is realized. In the future, new control systems can be designed based on the current one. When the engine simulator is connected with engine test bench and ECU, engine real-time simulation can be realized.

“…However, in the design and verification processes for a new engine, this requires a great deal of time and patience. Recently, many model based design methodologies have been proposed; for example, [1]- [11] for idle speed control, [12]- [21] for air-fuel ratio. Biblio for autmotive and engine control have also beed published [22], [23].…”

: The present paper describes a model representation of multi-cyclic phenomena for a multi-cylinder engine system. The model is simplified for implementation as a practical engine controller. The simplified model with physically meaningful variables can be used in design considering practical objectives and constraints more effectively. The proposed approach consists of two steps. First, an approximate analytical discrete crank angle model (i.e., a periodically time-varying state space model) is derived from the conservation laws. Second, the concept of role state variables is proposed to transform the periodically time-varying state space model into a time-invariant state space model. The stabilizability and optimality of the time-invariant state space model imply those of the periodically time-varying state space model. The time-invariant state space model is used to design cold start feedforward and feedback controllers.
