Abstract

ABSTRAKMotor induksi yang paling banyak digunakan juga memiliki kekurangan seperti losses yang cukup tinggi, power factor correction, dan efisiensi yang rendah. Oleh karena itu, dibutuhkan pengendali motor induksi yang memiliki performa dan efisiensi yang tinggi. Salah satu jenis AC – AC konverter yang mempunyai efisiensi, lifetime, kekompakan dan faktor daya mendekati unity yang akan digunakan sebagai pengendali motor induksi adalah matrix converter. Metode venturini digunakan sebagai modulasi pada matrix converter. Untuk itu dalam penelitian ini dilakukan pembuatan simulasi menggunakan simulink MATLAB dan hardware matrix converter. Pengujian matrix converter menggunakan modulasi venturini sebagai pengendali motor induksi telah dilakukan dengan motor dapat berputar mencapai kecepatan nominal sebesar 1440 Rpm sesuai nameplate dan motor juga dapat berputar dibawah frekuensi nominal. Dengan penelitian ini, pengendalian motor induksi dapat lebih efisien dalam penggunaannya di berbagai bidang.Kata kunci: Matrix converter, metode venturini, motor induksi. ABSTRACTThe most widely used induction motors also have disadvantages such as fairly high losses, power factor correction, and low efficiency. From this disadvantages, we need an induction motor controller that has high performance and efficiency. One type of AC-AC converter that has efficiency, lifetime, compactness and power factor approach to unity that will be used as an induction motor controller is a matrix converter. The Venturini method is used as modulation in the matrix converter. For this reason, in this study, simulation was made using MATLAB simulink and hardware matrix converter.

Abstract

Path planning is a crucial aspect of mobile robot navigation, ensuring that robots can safely travel from their initial position to the goal. In real-world applications, path planning is essential for autonomous vehicles, drones, warehouse robots, and rescue robots to navigate complex environments efficiently and safely. One effective method for path planning is the Rapidly-exploring Random Tree (RRT) algorithm, which is particularly practical in maze-like environments. The performance of RRT depends on the sampling methods used to explore the maze. Sampling methods are important because they determine how the algorithm explores the search space, affecting the efficiency and success of finding an optimal path. Poor sampling can lead to suboptimal or infeasible paths. In this study, we investigate different sampling strategies for RRT, specifically focusing on uniform sampling, Gaussian sampling, and the Motion Planning Network (MPNet) sampling. MPNet leverages a neural network trained on past environments, allowing it to predict promising regions of the search space quickly, unlike traditional methods like RRT that rely on random exploration without prior knowledge. This makes MPNet much faster and more efficient, especially in complex or high-dimensional spaces. Through a benchmarking analysis, we compare these methods in terms of their effectiveness in generating feasible paths. The results indicate that while all three methods are effective, MPNet sampling outperforms uniform and Gaussian sampling, particularly in terms of path length. The mean path length generated, based on a sample size of 30, is 13.115 meters for MPNet, which is shorter compared to uniform and Gaussian sampling, which are 18.27 meters and 18.088 meters, respectively. These findings highlight the potential to enhance path planning algorithms using learning-based sampling methods.

Abstract

This research describes a simple modeling technique for Maximum Power Point Tracking based on Artificial Neural Network (MPPT-based ANN) for photovoltaic (PV) systems. The proposed ANN model utilizes a feed-forward backpropagation architecture. The PV system was developed and tested in a simulation environment under uniform irradiation levels of 1000 W/m², 800 W/m², and 600 W/m², and rapidly varying irradiation changes. The simulation results demonstrate that the MPPT-based ANN accurately tracks the MPP, achieving stable power outputs of 98.36 W, 79 W, and 57.45 W, respectively. Although the system experiences initial transient oscillations during the tracking phase, it stabilizes within 80 milliseconds, showcasing rapid convergence and high steady-state accuracy. Under dynamic conditions, the MPPT-based ANN adapts effectively to fast-changing irradiation, restarting the algorithm to track and maintain the system at the updated MPP accurately. These results highlight the reliability, adaptability, and suitability of the MPPT-based ANN for real-time applications in dynamic environments. Nonetheless, further improvements to the ANN model are suggested to minimize transient oscillations and enhance overall performance.
