Abstract

This study explores the challenges of achieving precise positional control in three-phase AC motors, specifically in small industrial communities seeking to boost productivity with advanced motor systems. Although three-phase AC motors (0.25–1 kW) are efficient, they often face issues with control accuracy due to inherent inertia and long start-stop cycles. These motors typically take 1–2 seconds to reach full speed and 2–3 seconds to stop, causing disruptions in operations that require high precision and quick responses. To address these limitations, the research proposes an innovative control system designed to reduce startup time to 0.5 seconds and stopping time to 0.75 seconds. This system ensures precise positional halts, which is essential for applications such as automated production lines and specialized equipment like missile launchers. The control mechanism is fine-tuned for smooth synchronization with other subsystems, minimizing delays caused by slow motor responses. Tailored for small-scale industries, this solution tackles practical challenges by reducing downtime and improving accuracy in tasks that require short-duration actions. For example, it excels in rapid object tracking and locking, where delays could hinder target acquisition. By implementing this advanced motor control system in local industries, the research contributes to community empowerment, enhancing production efficiency, cutting operational delays, and fostering technological self-reliance. This approach highlights the transformative potential of modern motor control technology as a driver for industrial and economic growth, particularly in underserved regions where traditional systems are inadequate.

Abstract

This simulation represents a critical step in studying the waveform characteristics of the DC motor C42-L50 using a control system circuit with Linear Quadratic Regulator (LQR) and Linear Quadratic Tracking (LQT). Prior to initiating the simulation and data collection, a mathematical model was formulated using the datasheet of the DC motor C42-L50. Based on this model, further analysis was conducted, followed by simulations using MATLAB Simulink to explore and evaluate the differences between LQR and LQT in terms of the waveform or graphical characteristics of the DC motor. The analysis involved observing the simulation scope in MATLAB Simulink and experimenting with noise introduced into the system circuit. To align this study with community empowerment objectives, the findings aim to enhance the reliability and efficiency of DC motor applications in community service projects. For instance, the improved motor control facilitated by LQR and LQT methodologies can support the development of renewable energy solutions, agricultural automation systems, or other local technological advancements. This approach underscores the practical benefits of integrating advanced control systems into projects that promote sustainable community development.

Abstract

Direct current (DC) motors are among the most commonly utilized electric motors in various industries due to their robust and reliable regulatory characteristics. These motors also hold significant potential for application in community-based programs, particularly in renewable energy and small-scale mechanization projects that aim to empower underprivileged communities. To effectively analyze a DC motor system, it is essential to mathematically model its operational variables. This mathematical model is expressed as a transfer function, which is integrated into the simulation process using the Matlab Simulink platform. Typically, first- and second-order equations are used to represent these transfer functions. The optimization process involves the state-space representation to determine the K gain value, which is critical for achieving precise control. The Q value, derived from the multiplication of the C transpose and C matrix, directly influences the system's step response speed, while the R value is predetermined at 0.000001. Adjusting these parameters enables an optimized balance between response speed and system stability. This research provides a foundational framework for leveraging DC motor optimization in real-world applications, particularly in community empowerment programs. By enabling more efficient control mechanisms, this study contributes to the development of affordable and sustainable energy solutions, such as small-scale irrigation systems, local production facilities, or microgrid systems in remote areas.

Abstract

Electric motors are devices that convert electrical energy into mechanical energy. In a DC motor, this energy conversion occurs as a current flows through a coil in the stator, causing the rotor to rotate due to magnetic field repulsion. This research focuses on the application of DC motors in community service projects, particularly in systems that support sustainable development efforts in rural and underdeveloped areas. In such settings, DC motors are often used in various community development projects, including water pumping systems, small-scale energy generation, and agricultural machinery. The ease of controlling DC motors, particularly through advanced control systems, makes them ideal for these applications. This study investigates the impact of different control strategies on the performance of DC motors, specifically comparing SISO (Single Input, Single Output), SIMO (Single Input, Multiple Output), MISO (Multiple Input, Single Output), and MIMO (Multiple Input, Multiple Output) systems. Each of these systems offers unique advantages for controlling the motor's performance, such as optimizing speed, torque, and energy efficiency, which are critical in real-world community applications. The simulation results will provide insights into the advantages of each control system and highlight how these can improve the overall efficiency and reliability of systems that directly impact community welfare. The findings from this study are expected to be highly relevant for community service applications, offering practical solutions for enhancing the quality of life through better-designed technologies and optimized systems.

Abstract

This paper explores the application of a Single-Phase Full-Wave Uncontrolled Rectifier in renewable energy systems, with a focus on its potential for community empowerment in rural or underserved areas. The diode/rectifier plays a crucial role in converting alternating current (AC) to direct current (DC), which is essential for many electronic devices and renewable energy systems. The study evaluates the system’s efficiency, cost-effectiveness, and its ability to enhance energy accessibility, economic development, and sustainability within local communities. From the research include the importance of adjusting the ignition angle (α), which directly impacts the output voltage, current, and waveform. A smaller ignition angle results in lower output voltage and current, which can be particularly beneficial for managing fluctuating energy demands in off-grid communities. Additionally, the resistance in the rectifier circuit influences the current and waveform shape, with higher resistance leading to lower current crucial for designing energy-efficient systems for low-power communities. Lastly, changing the load value affects the rectifier's power output. Larger loads lead to reduced power output, highlighting the significance of scalable renewable energy systems to meet the varying needs of different communities. Overall, the study emphasizes the potential of this rectification system to improve the reliability, affordability, and sustainability of renewable energy solutions in underserved areas, contributing to local economic growth and development.
