Environmentally mediated systemic involvement of autoimmunity, allergy and carcinogenesis are very common by clinical and epidemiological investigation. However, there is an unknown relationship between environment and environmentally mediated systemic involvement of autoimmunity, allergy and carcinogenesis. This unknown molecular communication or response conducts the primary injury sites of t...

This paper contains the development of the identification with the black box method and PID control of the lifting process (on the Y axis) of a Quadrotor model GAUI 330X, The process involves the developing of the speed control loop within control angular speed of the motor and the sensor used was a CNZ1120 with its respective voltage-frequency converter. it is applied nonparametric methods Eye...

During this season, due to high running costs of the slewing loader,an exercise wascarriedout to compare the slewing loader and the hi-capacity Bell loaders. The slewing loader in use at the time was the model with high lift boom mounted on a Ford 6600, modified with a Brockhouse torque converter. The comparison revealed that, under the conditions obtaining at Mgayi section, the Bell loader was...

In solar photovoltaic (PV) system-based Brushless DC (BLDC) motors for water pumping application, the role of DC/DC converters is very important. order to extract maximum power from PV array, an efficient converter essential at intermediate stage. this work, different topologies suitable BLDC are proposed. The supported by optimized point tracking system provide a reliable operation. Recent opt...

In order to deal with the boost converter non minimum phase property and to solve the Sliding Mode Control (SMC) major problem (the chattering phenomenon), a new backstepping Sliding Mode Controller is developed. In this paper, a comparative study between the proposed controller and the (2-SMC)super twisting and the classical SMC is provided in order to evaluate each controller. Simulations and...

This paper presents super capacitor (SCAP) and battery modeling with an original energy management strategy in a hybrid storage technology. The studied dc power supply is composed of SCAPs and batteries. SCAPs are dimensioned for peak power requirement, and batteries provide the power in steady state. A bidirectional dc/dc converter is used between SCAPs and the dc bus. Batteries are directly c...

We designed and implemented a single-switch step-up DC-DC converter based on cascaded boost Luo converters. The proposed demonstrated quadratic voltage gain high efficiency, which makes it suitable for renewable energy applications, where ratio is desired without imposing number of bulky items or employing duty cycle the active switches. This benefits from continuity input current waveform, equ...

STUDY OF A HIGH-EFFICIENT WIDE-BANDGAP DC-DC POWER CONVERTER FOR SOLAR POWER INTEGRATION Yashwanth Bezawada Old Dominion University, 2017 Director: Dr. Yucheng Zhang This research focuses on the design and analysis of a Boost cascaded Buck-Boost (BoCBB) power converter with super high efficiency in electric power conversion. The BoCBB power converter is based on emerging wide-bandgap silicon-ca...

The positive output elementary Luo (POEL) converter is a fourth-order DC–DC having highly non-linear dynamic characteristics. In this paper, new voltage feedback controller proposed to achieve regulation of the POEL converter. contrast state-of-the-art current-mode controllers for high-order boost converters, control strategy uses only state variable purposes. This eliminates need inductor curr...
