This research aims to comprehensively analyze the most essential uses of artificial intelligence in Aerospace Engineering. We obtained papers initially published in academic journals using a Systematic Quantitative Literature Review (SQLR) methodology. We then used bibliometric methods to examine these articl...
A control strategy of space vector pulse width modulation(SVPWM) is proposed based on proportional integral(PI) control combined with improved proportional resonant(PR) controller.A method named with double closedloop control of voltage and current based on PI control is generally used in the traditi...
Differential quadrature provides a global approach to numerical discretization, which approximates the derivatives by a linear weighted sum of all the functional values in the whole domain. Following the analysis of function approximation and the analysis of a linear vector space, it is shown in the...

Because metaheuristics are very accurate and straightforward, they have drawn much attention in various challenging optimization issues in engineering, communications, medical, and social sciences5. Moreover, metaheuristic algorithms are also used to improve solutions for a variety of problems, such as ...
With the rapid development of renewable energy, photovoltaic energy storage systems (PV-ESS) play an important role in improving energy efficiency, ensuring grid stability and promoting energy transition. As an important part of the micro-grid system, the energy storage system can realize the stable...
modulation (PWM) and space vector modulation (SVM) are among the most prominent and most widely used strategies to control the operation of an inverter. The PWM technique is simple, easy to perform, and inexpensive compared to the SVM technique. But the SVM technique is more efficient and ...
