Abstract

The presence of a controller in a control system plays a significant role in determining the behavior of the system. Fundamentally, this is due to the inherent properties of the system components, which cannot be altered. Consequently, the system's behavior can only be modified by introducing an additional system component, namely the controller. Modern control systems, enhanced with optimization techniques, have evolved into advanced modern control theories and robust control systems widely applied in industrial settings. Optimization and control systems primarily utilize frameworks such as MIMO (Multiple Input Multiple Output), SIMO (Single Input Multiple Output), MISO (Multiple Input Single Output), and SISO (Single Input Single Output), which are built on the principles of diversity and adaptability. This research focuses on applying Linear Quadratic Regulator (LQR) and Linear Quadratic Tracking (LQT) methods in optimizing DC motor control systems, using MATLAB Simulink to support energy efficiency programs for small-scale industries. The integration of these control methods is not only aimed at improving system performance but also at addressing the needs of micro-entrepreneurs through practical and implementable solutions, fostering social and economic development. The study findings contribute to community service initiatives by introducing energy-efficient technologies that empower small business owners to adopt sustainable practices. This aligns with the broader goal of bridging technological advancements with societal impact, providing a pathway for scalable and practical applications in real-world settings.

Abstract

The increasing demand for electricity in modern society necessitates innovative solutions, particularly in rural areas with limited access to reliable energy sources. Solar power, utilizing photovoltaic (PV) technology, has emerged as a sustainable energy solution. However, the challenge lies in ensuring that the voltage output from solar panels aligns with the requirements of energy storage systems, such as batteries. This research explores the application of a SEPIC converter as a voltage stabilizer for a 30W solar panel, aimed at improving the reliability of renewable energy in rural communities. In this study, two 30Wp polycrystalline solar panels are configured in series to generate a variable output voltage ranging from 5V to 17V. To charge a 24V battery, a SEPIC converter is employed to adjust the voltage, ensuring that it meets the battery's requirements. The converter's duty cycle, controlled by an Arduino Uno, regulates the voltage output. Testing reveals that the SEPIC converter successfully stabilizes the output voltage, with an average of 24.26V, meeting the desired set point. This solution provides a reliable and sustainable energy source for rural communities, promoting the use of renewable energy while addressing the voltage stability issue. The study highlights the practical application of the SEPIC converter in enhancing energy access and supporting community empowerment through renewable technology.

Abstract

This study compares the performance of the Linear Quadratic Regulator (LQR) and Linear Quadratic Tracking (LQT) methods in controlling a limited oscillatory mechanical system, with a focus on their potential applications in community-based technology empowerment programs. The comparison was conducted using numerical simulation techniques, with key performance indicators such as mean squared error (MSE) and convergence time. The results show that the LQR method outperforms LQT in controlling the oscillatory system with more consistent accuracy and faster convergence. However, LQT demonstrates superior flexibility and robustness in handling more complex scenarios and unexpected perturbations. These characteristics make LQT particularly suitable for applications in dynamic environments, such as those found in local industries or community-driven projects. The choice of method ultimately depends on the specific requirements and conditions of the system being controlled. This research contributes to community development by exploring efficient control strategies that can improve local industrial systems, leading to better energy utilization and productivity, which in turn supports sustainable economic growth within the community.

Abstract

DC motors are widely used in various sectors, including industrial applications, household appliances, and even children's toys. This research presents a system identification process for a DC motor using experimental techniques with the system identification tool in Matlab. The study explores optimal control techniques, specifically Linear Quadratic Regulator (LQR) and Linear Quadratic Tracker (LQT), to analyze the step response of the system. Understanding the transfer function of the DC motor is crucial for effective control; this is achieved by adjusting the Q and R matrices in the LQR technique, which ultimately modifies the value of the feedback gain, K. The Linear Quadratic Tracking (LQT) system aims to adjust the output to follow a predetermined trajectory, offering a dynamic tracking solution. To apply these control techniques, the DC motor is first modeled in the Laplace domain of order 2 and then transformed into the state-space domain, allowing for integration into LQR and LQT calculations. In this study, noise is introduced to assess the system's performance under both normal and noisy conditions, highlighting the resilience of the control methods. The control process, including the simulation and implementation of LQR and LQT calculations, is conducted using Simulink in Matlab. This research is of particular relevance to community empowerment initiatives, where the principles of optimal control can be applied to improve local technological solutions. The application of these control techniques to affordable, low-cost DC motor systems can significantly contribute to the development of sustainable technology in underprivileged communities, enhancing the accessibility and efficiency of small-scale industrial solutions. The findings aim to support practical applications in fields such as renewable energy, agricultural machinery, and local craftsmanship, offering a pathway to economic growth through technology.

Abstract

Energy demand in Indonesia, as well as globally, continues to increase. Hydroelectric power plants (HEPP), along with steam power plants (SPP) and gas power plants (GPP), play a crucial role in electricity supply. Indonesia, an archipelagic country located along the equator, is uniquely positioned with abundant wind energy potential. Remote communities, which often face challenges in accessing electricity, could benefit from utilizing this renewable resource. The ventilator turbine, primarily designed for air circulation, is installed on rooftops of residential and industrial buildings to function as ventilation. Previous research has explored the use of ventilator turbines as wind-powered electricity generators, yet several improvements are still needed. This research focuses on enhancing the performance of the ventilator turbine by connecting the wind turbine to a generator through a V-belt system, which maximizes the rotational speed and energy output. The generator then produces electricity that can be utilized by local communities, providing a sustainable and eco-friendly energy solution. This research aims to contribute to community empowerment by introducing renewable energy technologies that can be locally maintained and managed, thus promoting economic independence in rural areas.

Abstract

Optimization plays a critical role in systems related to technology and engineering, particularly in efforts to enhance community empowerment through technology adoption. In this study, optimization is applied to improve the efficiency of community-oriented technology by leveraging optimal control techniques. Specifically, a Linear Quadratic Regulator (LQR) is employed to analyze the step response of the system and its reaction to disturbances, providing precise control for community technology applications such as crafting machines or energy-efficient devices. Before implementing LQR control, simulations using MATLAB Simulink are conducted to determine the optimal gain parameters for the control system. Additionally, Linear Quadratic Tracking (LQT) is utilized to design a closed-loop control scheme aimed at ensuring the system's output signals optimally track the reference signals and effectively reject disturbances. This method provides a robust approach to optimizing devices that directly impact productivity and cost-efficiency in community programs. The proposed solution is formulated by converting the LQT problem into a standard Linear Quadratic Regulation problem, ensuring adaptability for practical implementation. The approach is demonstrated through two simulation examples: a first-order generator and a second-order generator, with the simulation results presented and discussed in detail. These findings highlight the potential of LQR and LQT optimization in improving technological applications in community development programs, contributing to enhanced social and economic outcomes.
