This paper proposes pulse width modulation (PWM) methods for low inductance brushless DC (BLDC) motor drives that minimize the commutation torque ripples. An uneven current of non-commutation phase generates In BLDC drives, two types time delays in PWM also induce critical this paper, analyses and their effects are introduced. Then, proposed to eliminate region conduction region, respectively. ...

Technological developments are increasingly rapid, especially in the field of transportation, electric vehicles, which triggered by increasing scarcity fossil fuels. One propulsion engines that widely used vehicles is brushless direct current (BLDC) motor because this has high torque, constant speed and easy to regulate. This study aims design a BLDC control using boost converter as voltage inc...

This paper reviews the recent developments in the field of sensorless control of Brushless Direct Current motors. Moreover a survey of application of H∞ control theory for robust control, considering the uncertainties like modeling errors and external disturbances in various motors and systems has been carried out. This provides a deeper insight into the recent developments and future scope in ...

The paper presents our efforts in defining UASM, a unified syntax for Abstract State Machines (ASMs), based on the syntaxes of two of the main ASM frameworks, CoreASM and ASMETA, which have been adapted to accept UASM as input syntax of all their validation and

• Durch die starke Vernetzung ehemals unabhängiger Funktionen ergeben sich ungewollte Interaktionen und Seiteneffekte durch Nebenläufigkeit. Als Beispiel sei hier die Zentralverriegelung genannt, die neben der reinen Funktionalität des Verund Aufschließens mit Komfortfunktionen zum Einstellen von Sitz, Spiegeln und Radiosendern in Abhängigkeit vom verwendeten Schlüssel, mit Sicherheitsfunktione...

<p class="Abstract">Brushless DC motor (BLDC) is one type of electric that widely used, especially in automotive systems. This used as a driving force vehicles. BLDC chosen because it has the characteristics high efficiency, reliability, and wide speed range. Besides, motors require less maintenance can operate quieter than motors. Even though many advantages, its application use vehicles...

Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...
