    Design and Simulation of Z-Source Inverter Fed Brushless DC Motor Drive Supplied With Fuel Cell for Automotive Applications

    By Abolfazl Halvaei Niasar, Mohsen Teimoori, Sayyed Hossein Edjtahed

    Abstract: This paper presents design and simulation of Z-source inverter fed brushless DC motor drive supplied with fuel cell for automotive applications. The brushless DC (BLDC) motor are used due to many advantages such as high efficiency, high torque, high reliability, high-power density, lower maintenance compared to other motors in electric transport applications. The BLDC motor drive is with voltage source inverter (VSI) or current source inverter (CSI) because of low …

    Control of BLDC Motor using Fractional-order PID Controller Optimized by ICA

    By Abolfazl Halvaei Niasar, Saber Falahati Aliabadi

    Abstract: In this paper a new method for speed control of BLDC motors is proposed. In this method, fractional order PID (FOPID) is used for control of BLDC motor. In order to determine the parameters of FOPID controller imperialist competitive algorithm (ICA) is employed for its high speed and accurate for solve of optimization problems. In order to verify the performance of proposed controller, some simulations have been carried out with …

    A Novel Sensorless Vector Control of High-speed Hysteresis Motor Drive

    By Mohammad Zare, Abolfazl Halvaei Niasar

    Abstract: Hysteresis motors are super high speed motors that used in special industries such as high-speed centrifuges, micro gas turbines, and etc. They are basically synchronous motors; however they can works in asynchronous mode. In most reported applications it is controlled in open-loop scheme and there isn’t any considerable research on closed-loop control of this type of motor due to its special and limited applications. This papers presents a novel filed …

    Power System Stabilizer Design based on Honey-Bee Mating Optimization Algorithm

    By Abolfazl Halvaei Niasar, Dariush Zamani

    Abstract: Power system stability is one of the main factors in performance of electrical system. A control system must retain frequency and voltage size under any distortion such as sudden increase in load, to leave a generator from circuit or cut off a transmission line in a constant level. In this paper, Honey-bee mating optimization (HBMO) algorithm has been used to design power system stabilizer. It is based on the mating …

    Conversion of Gasoline Vehicles to CNG Hybrid Vehicles (CNG-Electric Vehicles)

    By Abolfazl Halvaei Niasar, Hassan Moghbelli

    Abstract: Operating CNG vehicles are really beneficial in the Middle East region considering the fact that gasoline is offered at a heavily subsidized price and therefore, by converting a significant portion of the automobiles to run on CNG, the gasoline internal consumption could be reduced. This in turn will result in more oil being available for export which will be beneficial to the economy of Qatar. Hybrid Vehicles mainly have a …
