Abstract

Rapid technological advances have had a significant impact in various fields, including occupational safety and health (OSH). In industrial operations, electric motors play an important role in supporting work efficiency and safety. This study aims to analyze the performance of DC motors C23-L54 Series using Linear Quadratic Regulator (LQR) and Linear Quadratic Tracker (LQT) controllers to improve operational efficiency and safety in K3-based systems. Modeling is carried out using a state-space approach, which allows for complex analysis of the input-output relationship of the control system. The simulation was conducted through MATLAB Simulink R2018a with a voltage input of 0.5 V. Initial simulation results show that the unmanned system experiences large oscillations and instability, which has the potential to increase the risk of operational failure and harm to workers. To solve this problem, LQR and LQT controllers are designed to stabilize the system and eliminate oscillations, both in no-noise and noisy conditions. The test was carried out on the mathematical model of order 1 and order 2 using step signals with setpoint values of 0.848 and 0.01905. The results show that the designed controller is able to significantly improve the stability of the system, thereby reducing the risk of device damage and potential work accidents. These findings make a significant contribution to the integration of advanced control technologies to support occupational safety in industrial environments. This research is expected to be a reference in the development of safe and efficient electric motor-based 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.
