“…In recent years, WTG is developing from fixed pitch to variable pitch. In the high wind speed section, the pitch angle controller starts to function, changing the pitch angle of the fans, and limits the energy captured by the WTG, thereby limiting the fan speed and output power to the rated value [1][2][3][4]. In order to achieve a better control, many researchers have done a lot of researches.…”

When the wind speed is above the rated value, the output power of the wind turbine should be maintained at the rated value in order to prevent the power generation system from overheating. In addition, the natural wind speed will fluctuate randomly in a large range of values, making the traditional control effect not ideal. This paper presents a novel H-infinity (H ∞ ) pitch control strategy for Wind Turbine Generators (WTGs), which can make the rotor speed and output power constant when the wind speed changes in a large range. In order to shorten response time and reduce overshoot, in the specific solution, the control method combines the H ∞ theory and the Takagi-Sugeno (T-S) fuzzy theory. Firstly, the linearized models of several operating points were obtained with the T-S fuzzy theory. Then, a robust controller was designed for each linear sub-system based on the H ∞ control theory. Furthermore, the controllers of the sub-systems were superimposed into a global controller for the entire system through the membership function. Finally, modeling and simulation were carried out in MATLAB/SIMULINK. The simulation results show that when the wind speed changes above the rated speed, the rotor speed can be maintained at the rated value, and the output power also can be maintained at the rated value. Compared with the optimal control, the response speed of this method is faster and the overshoot is smaller. It provides a new idea for the pitch angle control of wind turbine.

“…Hydrogen fuel is a kind of green, renewable, clean energy source that can provide powerful output for automobiles, and it has a very huge development potential [1][2][3][4][5][6][7]. Hydrogen storage is the largest constraint on hydrogen engines and hydrogen fuel cells used in electric vehicles and hybrid electric vehicles [8][9][10][11][12][13]. Compared with zirconium-based, titaniumbased, and rare earth elements-based hydrogen storage alloys, the magnesium-based hydrogen storage alloy has a few merits including light weight, excellent discharge performance, long cycle life, and large hydrogen storage capacity, thus it has a very good prospect to be applied in the market of lightweight automobile.…”

The magnesium-based hydrogen storage alloy has a very good prospect to be applied in the market of lightweight automobile due to its merits of light weight, excellent discharge performance, long cycle life, and large hydrogen storage capacity. However, existing studies on magnesium-based hydrogen storage alloy have a series of shortcomings such as the insufficient works in terms of model reasonability analysis, heat transfer behavior analysis, heat control scheme design, and comparative experiment analysis, etc. In view of these problems, this paper studied the thermal effect and heat control strategy of the Mg-based Hydrogen Storage Alloy (MHSA) system for lightweight automobile. At first, this paper constructed numerical models for the fluid-solid coupled heat exchange region and the heat conduction region in the system; then, based on the law of energy conservation, a heat transfer behavior model of the MHSA system was established and used to analyze the thermal effect of the system. After that, according to the driving process of hydrogen fuel cell electric vehicle, the working process of the MHSA system was further analyzed to study the heat control process. Next, this paper proposed a new idea for the heat control of the MHSA system, gave a few tips for the simulations, and presented the flow of the heat control scheme of the system. At last, the experimental results were given and analyzed.

“…The demand for energy around the world is increasing rapidly due to the growth of industrialization and urbanization. Due to this increase in energy demand, economic policy must change from conventional mechanisms to energy-saving machines or in the form of energy recovery or using green energy technology [1][2][3][4]. For energy recovery, example, the smoke or flue gas coming out of the chimney can be used for heat energy by a thermoelectric generator (TEG) to produce electrical energy, thereby increasing system efficiency.…”

Increasing the ability to harvest thermal energy on the hot-side of the thermoelectric generator (TEG) module is a challenge for researchers to increase the electrical conductivity of the module. This study aims to increase the absorption of solar heat on the TEG module by adding carbon and copper layers with the electroforming method. The ultimate goal is to increase the electrical energy generated by TEG. The process of adding carbon by painting, while the copper layer by dyeing. The voltage during immersion varied from 2.5, 3, and 3.5 Volt with copper plating durations of 30, 45, and 60 minutes. The results show an increasing trend of solar thermal absorption during testing under the hot sun. The longer it is immersed in the copper layer, the greater the output power of the TEG module. The safe immersion of the module for 45 minutes in Cu solution brought the best positive effect. As a comparison, the output power produced by the TEG module without copper coating is only about 0.000025 Watt for a light intensity of 881.67 Watt/m 2 . After coating, the power generated was increased by 25.1 times at the same intensity. Measurements of temperature and power generated are measured by applying the LabVIEW software application from National Instrument.
