In view of the control problem of hydrogen pressure and flow coupling in the anode subsystem of the Proton Exchange Membrane Fuel Cell (PEMFC) under dynamic load conditions, this paper proposes an intelligent control framework based on the deep deterministic policy gradient (DDPG) algorithm. Firstly, a dynamic model of the fuel cell anode system is established to transform the multivariable coupling control problem into a reinforcement learning state space; secondly, a multi-objective reward fun...

This thesis aims to determine the most suitable topology by comparing the advantages of input power redundancy architectures used in avionics units for military aircraft (HA). Redundancy architectures for input power of avionics units were investigated, analyzed using LTSpice and the PCB design was optimized according to the analysis results. Then, based on the experimental and simulation results, the most suitable redundancy architectures were determined according to the criticality levels of a...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor. DC motors are widely utilized in various applications due to their simplicity and efficiency; however, robotics and automation are only performed effectively through proper control of the operational parameters. This research aims to develop a strong motor control system that can dynamically chang...

In the contemporary world, energy is a very important factor for economic development, especially when a country is in the process of accelerating its economy into an industrialized one, as in the developing countries like Mongolia. The nexus between energy consumption and economic growth has been widely studied by various researchers from different countries. This study investigated the causal relationships (i.e., the short- and long-term structural associations) between the gross domestic prod...

The advancement of modern power electronics technology has elevated the importance of inverter systems within power applications, where their reliability is pivotal to the overall stability of power systems. Among the primary challenges faced are bus short-circuit faults, which can arise from external natural factors, internal aging, and installation issues. These faults often result in significant equipment damage and economic losses. This paper explores the synergistic application of fault det...

The economic dispatch problem in power systems is a classic issue in the field of power systems. This paper first uses the traditional genetic algorithm to solve the economic dispatch problem of power systems. The simulation results show that the classic genetic algorithm falls into the dilemma of local minimum values. Therefore, we introduce a multi-population genetic algorithm, setting different crossover and mutation probabilities in different populations, and introducing an immigration opera...

This study compared Inertial Measurement Unit (IMU) and Optical Motion Capture (OMC) systems in measuring peak ankle angles and Range of Motion (ROM) during Countermovement Jumps (CMJ) and Lateral Skater Jumps (LSJ). Data during these agility movements were analyzed and the ankle angles in pitch, roll, and yaw for the IMU were determined using algorithms which integrated gyroscope data, aligned it with foot flat reference, and fused it with accelerometer-derived inclination angles using a comple...

Electricity is vital for modern society, powering homes, industries, hospitals, and transportation systems. It is the backbone of our daily lives, enabling convenience, fulfilling human basic needs, and crucial for the development and improvement of socioeconomic conditions. However, the Democratic Republic of the Congo faces a significant challenge with low electrification rates, where less than 10% of the population has access to electricity. Even the capital city, Kinshasa, with 17 million in...

The main determinant of the cost price of a solar panel in the market is the rated peak power as measured under standard laboratory conditions (cell temperature of 25?C, solar irradiance of 1000 W/m2 and an air mass of 1.5). An indirect method (considered indirect since the measurement is done under nonstandard laboratory conditions) is adopted here in order to approximate with some degree of certainty the rated peak power of a solar panel. It involves the use of a characterized solar module of ...
