Abstract

DC motors are widely utilized in industrial applications for their reliability and efficiency. To optimize their performance, it is crucial to employ control systems supported by mathematical modeling to predict motor responses under varying conditions. This study investigates the first- and second-order models of DC motors and examines the impact of internal disturbances (noise) on system performance. The output responses of two DC motors, the 42BLFX02 and Maxon EC-I 40 (70W), are compared under both undisturbed and noisy conditions using simulations. The results reveal that the second-order model offers a more stable response and better aligns with the desired target compared to the first-order model. Furthermore, the application of the Linear Quadratic Regulator (LQR) control method significantly enhances the speed and accuracy of reaching the motor set point. However, when noise is introduced, the LQR method fails to maintain stability, and the motor's output starts to mirror the disturbance pattern. These findings highlight that while LQR is effective under ideal conditions, its performance diminishes when exposed to disturbances. Therefore, additional strategies are necessary to ensure stability and optimal performance in real-world conditions, particularly in environments with significant noise or disturbances.

Abstract

A DC motor is commonly utilized as an actuator due to its ability to produce high torque. Controlling the motor's speed is one of the primary methods to manage its performance. Among various wireless communication options, radio waves are preferred since they do not require a clear line of sight between the transmitter and receiver. Employing multiple antennas offers benefits such as enhanced reliability and increased data transmission rates. This study focuses on designing and simulating four types of systems: SISO, SIMO, MISO, and MIMO. The performance of these configurations is evaluated and compared using Signal-to-Noise Ratio (SNR) and channel capacity, with variations in antenna count. Simulations were carried out in MATLAB to analyze how different antenna quantities (4, 8, and 16) affect channel capacity across an SNR range of 0 to 30 dB. The simulation outcomes reveal a substantial rise in system capacity, reaching up to 214 bits/Hz/sec when a 16x16 MIMO setup is applied at 30 dB SNR.

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

In the field of education, particularly in marine electrical engineering, knowledge of single-phase capacitor motors is essential. To equip students with a solid understanding of the principles and operation of single-phase capacitor AC motors, appropriate infrastructure and learning tools, such as trainer kits, are required. A trainer kit functions as a basic educational tool that enhances comprehension of single-phase capacitor induction motors, which is crucial for students studying specialized courses in electrical motors. This tool enables various practical experiments, such as measuring the insulation resistance of motor windings, reversing the motor's rotation, testing the starting process of capacitor motors, and analyzing the power factor of capacitor motors. Additionally, a single-phase induction motor with a capacitor start can be used as a split-phase motor. The starting current in a split-phase motor is higher compared to a capacitor-start induction motor because the capacitor increases the starting power, resulting in a smaller current compared to the split-phase motor.

Abstract

Induction motors, which operate continuously, such as those used in power plant cooling systems, are at risk of failure that can result in significant losses, such as power outages when the turbine halts due to overheating. Therefore, it is crucial to have a system that monitors the temperature of the induction motor to detect potential overheating and facilitate maintenance. This study aims to design and test a temperature monitoring system for induction motors using thermocouple sensors connected to an LCD display. The methodology begins by identifying issues related to motors running non-stop, followed by a review of relevant literature and system design. Once the system was built, testing was conducted by heating the probe and measuring the temperature with a thermometer to compare the readings with those from the thermocouple sensor. The test results showed that the system accurately displayed the temperature on the LCD, with an error margin that was calculated to evaluate the sensor's accuracy. Based on these results, it can be concluded that the temperature monitoring system functions well and can be used as a reliable overheat detection system for induction motors. This system is expected to simplify maintenance processes and reduce the risk of motor damage caused by overheating. Additionally, the integration of this technology in community-based power plant initiatives could enhance the sustainability and safety of rural energy projects, ensuring a more reliable power supply for community empowerment programs.

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.
