Abstract

This paper presents a comparative analysis of classical PID control techniques and modern control approaches in the Eddy Current Brake Dynamometer system. Eddy Current Brakes, as modern braking systems, require efficient control mechanisms to enhance their performance. Traditionally, PID control has been widely employed; however, it is often deemed suboptimal in certain scenarios. To address these limitations, this study explores the development of a more modern and optimal control system utilizing Full-State Feedback Linear Quadratic Regulator (LQR). The comparative analysis of braking response times was simulated using MATLAB/Simulink. Results demonstrate that LQR control outperforms PID control in terms of braking response, with a settling time (Ts) of 2.12 seconds, a rise time (Tr) of 1.18 seconds, and zero overshoot. Conversely, while PID control achieves faster Ts (0.27 seconds) and Tr (0.18 seconds), it exhibits an overshoot of 0.7%, which may impact system stability. Furthermore, this research underscores the potential of integrating LQR-based control systems into community-oriented technical training programs. The improved performance metrics of the LQR control can enhance the practical learning experience, particularly in vocational education aimed at equipping underserved communities with advanced technical skills. By leveraging these findings, the study highlights the importance of adopting innovative control strategies to bridge the gap between theoretical knowledge and practical application, contributing to sustainable skill development initiatives.

Utilizing a stable oscillator circuit, the frequency parameters of a single-phase motor can be controlled by modifying the variable resistor value. A thyristor-based trigger circuit is employed to manage the motor's rotational speed by adjusting the trigger phase angle, which directly influences frequency and motor speed. Simulations conducted using PSIM software demonstrate the relationship between variable resistor adjustments and changes in motor rotation frequency. These simulations analyze the rotational behavior of single-phase motors based on the transformer output voltage, providing a foundational understanding of electronic circuit functionality. By leveraging PSIM, this study minimizes potential failures in practical circuit applications, contributing to enhanced technical education and skill development. The findings have significant implications for community-based technical training programs, equipping individuals with practical knowledge in electronic motor control systems and fostering community empowerment through applied technical education.

Among the various control methods available, Linear Quadratic Regulator (LQR) and Linear Quadratic Tracking (LQT) are two prominent techniques used to achieve optimal performance in dynamic systems. In this study, we applied the LQR and LQT methods to optimize the performance of a PG45RS775 DC motor, a key component that could be used in community-based applications, such as small-scale industrial production or educational workshops. The results indicated that the LQR method achieved the desired set point with a lower overshoot compared to LQT, demonstrating its potential for applications requiring precision and stability. Additionally, in real-world systems, noise or disturbances are often present, which can negatively affect the performance of control systems. In this research, noise was introduced into both LQR and LQT systems, and its impact on the output was analyzed. The addition of noise resulted in a noticeable increase in overshoot, especially within the LQT system.

Abstract

DC motors are widely used in both industrial and everyday applications due to their versatility and reliability. To optimize the performance of DC motors, implementing an effective controller is essential to ensure efficient operation under varying conditions. Modeling plays a critical role in evaluating whether the intrinsic response of a DC motor, even before being subjected to load, meets performance expectations. Common modeling techniques include SISO (Single Input Single Output), SIMO (Single Input Multiple Output), MISO (Multiple Input Single Output), and MIMO (Multiple Input Multiple Output). Accurate plant modeling requires the mathematical representation of the system to visualize its response graphically, often aided by specialized software. This study focuses on first-order and second-order mathematical models of DC motors, analyzing their behavior under different configurations and disturbances. Real-world systems are inevitably affected by disturbances, including internal noise, which can significantly influence system performance. The primary objective of this research is to compare the response characteristics of a 42BLFX02 DC motor under first-order and second-order mathematical models when configured as SISO, SIMO, MISO, or MIMO systems, with and without noise interference. The findings reveal that the SISO configuration without noise interference delivers the most stable and linear response, free of ripples. Second-order mathematical models produce responses closer to the setpoint compared to first-order models. In MISO and MIMO configurations, the system's output response tends to mirror one of the input signals. The introduction of noise significantly alters the output response, causing it to emulate the noise pattern.
