This paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. The design goal of the control strategy is to minimize fuel consumption and engine-out NOx, HC and CO emissions on a set of diversified driving schedules. Seven facility-specific drive cycles are considered to represent different driving scenarios. For each fa...

Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years...

From the EMC point of view, the integration of electric drive systems into today’s cars represents a substantial challenge. The electric drive system is a new component consisting of a high-voltage power source, a frequency converter, an electric motor and shielded or unshielded high-power cables. Treating this new electric drive system or its components as a conventional automotive component i...

کنترل موتور القایی، بدلیل وفور استفاده از آن، از دیر باز دارای اهمیت زیادی بوده است. کنترل برداری یکی از روش های کنترل موتور القایی می باشد که دارای مزایا و معایب خاصی است. اخیرا استفاده از روش های کنترل غیر خطی و بخصوص کنترل مقاوم و تطبیقی برای این نوع موتور مرسوم شده است. در این پایان نامه، ابتدا کنترل سرعت (گشتاور) و شار موتور القایی باستفاده از روش های غیر خطی، مورد بررسی قرار گیرد. از جمله...

Spin is the only internal degree of freedom of an electron, and that raises two interesting, closely related questions. First, what kind of new physics emerges when the processes traditionally attributed separately to electron charge and electron spin become closely interconnected? And second, to what sort of new electronic devices might this physics lead us? Success in applications has the pot...
