Abstract

Traditional storage cabinets that rely on conventional locks and provide unrestricted access are highly vulnerable to theft. To safeguard documents and other valuable items from loss, an integrated security system is required to regulate and secure access to storage compartments. This study aims to develop a security system based on facial recognition, ID cards, and a keypad interface The Haar Cascade classifier combine with LPBH utilizing the OpenCV library is employed for facial identification by storing 30 photos per person in a designated folder, and subsequently comparing facial objects captured by a webcam against pre-stored and trained facial data in the database. The analysis indicates that the optimal detection range of the system is between 100 and 300 cm. In facial orientation testing, the best recognition performance is achieved at angles between 0° and 40°. Based on 20 experimental trials, the system demonstrates an average success rate of 80%. These results suggest that a facial‑recognition‑based security system utilizing the Haar Cascade approach is feasible for implementation as a protective mechanism for storage cabinets.

Abstract

Load Frequency Control (LFC) plays an essential role in maintaining frequency and power stability in power generation systems under load disturbances. Variations in load demand, such as increases or decreases, may lead to power deviations that affect system reliability; therefore, an effective control strategy is required. This study evaluates the performance of an LFC system by comparing a Proportional–Integral–Derivative (PID) controller and a Fuzzy Logic Controller (FLC). The system is modeled based on the dynamic characteristics of the governor, turbine, and generator of a coal-fired steam power plant. System performance is analyzed under three operating conditions: no disturbance, load increase, and load decrease. The evaluation focuses on maximum power deviation and settling time as performance indicators. Simulation results show that both controllers are able to maintain system stability but with different dynamic characteristics. Under no-disturbance conditions, the PID controller reaches stability faster with a settling time of 18.126 s, while the FLC requires 28.038 s. During load increases, the PID-controlled system stabilizes at 194.652 s, whereas the FLC reaches stability at 200.524 s. For load reductions, the PID controller stabilizes at 194.378 s and the FLC at 196.559 s. In terms of maximum power deviation, the FLC produces a smaller deviation (0.41%) compared to the PID controller (0.47%). These results indicate that the PID controller provides faster recovery, while the FLC offers smoother responses with smaller deviations, showing potential for improving LFC performance.
