In development of Homogeneous Charge Compression Ignition (HCCI) engines, simultaneous control of combustion phasing and power output has been a major challenge. In this study, a new strategy is developed to control the engine power output and combustion phasing at any desired operating condition. A single zone thermodynamic model coupled to a full kinetic mechanism of Primary Reference Fuels (...

In the current world, the debate on the reinstatement and reuse of consumer prod-ucts has become particularly important. Since the supply chain of the closed loop is not only a forward flow but also a reverse one; therefore, companies creating integ-rity between direct and reverse supply chain are successful. The purpose of this study is to develop a new mathematical model for closed loop suppl...

In [8] a new model validation method was proposed that is based on the estimation of an unbiased model of the model error which relates the inputs to the simulation errors. In this paper, we extend this methodology to closed-loop validation, i.e. the validation of an open-loop model on the basis of closed-loop validation data. We show that, perhaps surprisingly, the same model may fail to be va...

Most scientiic computations spend a signiicant part of their time in the execution of loops. As a result, compiler designers for high-performance computer architectures have been focusing their attention on the eeective and eecient exploitation of parallelism within loops. In this paper, we use dataaow graphs as our program representation for a class of loops, and we develop a timed Petri-net m...

accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. in this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...

Model checkers for program verification have enjoyed considerable success in recent years. In the control systems domain, however, they suffer from an inability to account for the physical environment. For control systems, simulation is the most widely used approach for validating system designs. We present a new technique that uses a software model checker to perform a systematic simulation of...
