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

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.
