Abstract

Understanding the principles of physics, especially in a 2-loop electrical circuit, requires applying Kirchhoff's Laws to form a system of linear equations. While substitution-elimination methods are commonly used to solve these systems, they become inefficient when dealing with more than three variables. As an alternative, Cramer's Rule, which involves using matrix determinants and the cofactor method, proves to be more effective, particularly for larger systems. The research shows that both Cramer's Rule and the matrix inversion method produce consistent results for current calculations. The current values obtained from the first and second circuits match those calculated using the cofactor method. These techniques are not limited to electrical circuits; they can also be applied in other engineering fields, such as dynamic systems analysis and mechanics. A solid understanding of Cramer's Rule, cofactors, and matrix inversion is essential for analyzing both physical and engineering systems. In the first circuit, the results are i₁ = 0.25 A, i₂ = 2.5 A, and i₃ = 2.75 A, while in the second circuit, the results are i₁ = 1 A, i₂ = 2 A, and i₃ = 1 A.

Abstract

Pada penelitian ini, dilakukan pemecahan masalah rangkaian listrik menggunakan dua metode yang berbeda, yaitu metode invers matriks MATLAB dan metode eliminasi Gauss-Jordan secara manual. Dalam rangkaian listrik, analisis jaringan dilakukan untuk mencari arus atau tegangan pada berbagai titik dengan menggunakan hukum Kirchhoff, baik hukum arus (KCL) maupun hukum tegangan (KVL). Metode pertama yang digunakan adalah metode invers matriks MATLAB, di mana rangkaian listrik yang melibatkan banyak komponen (resistor, sumber tegangan, dan arus) dapat dianalisis dengan menyusun persamaan linear yang mewakili rangkaian tersebut. Matriks koefisien kemudian dihitung inversnya untuk mendapatkan solusi langsung terkait dengan sistem persamaan aljabar linear yang terstruktur. Metode kedua adalah eliminasi Gauss-Jordan manual, yang memungkinkan pemecahan sistem persamaan linear simultan secara bertahap melalui usaha perlakuan terhadap baris elementer yang ditujukan untuk matriks koefisien. Teknik ini dapat digunakan untuk memperoleh solusi tanpa bantuan perangkat lunak, dengan mengubah matriks menjadi bentuk eselon tereduksi hingga solusi akhirnya diperoleh. Kedua metode tersebut memberikan hasil yang dapat dibandingkan untuk memastikan keakuratan perhitungan arus dan tegangan dalam rangkaian listrik. Meskipun metode MATLAB lebih efisien dan cepat, metode Gauss-Jordan manual menawarkan pemahaman yang lebih mendalam tentang proses penyelesaian sistem persamaan secara manual. Kedua pendekatan ini dapat digunakan sesuai dengan kebutuhan dan kompleksitas analisis rangkaian listrik yang dihadapi.

Abstract

Based on the research study on the design of the Remote Distance Recording Automation Tool for PDAM Water Distribution Using WIFI, several conclusions can be drawn. The PDAM water usage recording device, which uses the Water Flow YF-S201 sensor on a microcontroller installed in the PDAM water distribution flow, can accurately read the volume of water flowing through the sensor. Experiments showed that the sensor achieved an average accuracy of 98.9% for water volumes ranging from 1.5 liters to 15 liters. This demonstrates the sensor's high precision in measuring water flow.To build the hardware and software circuit, the ESP8266 WiFi module was used on the atmega328 microcontroller. The data sent to the server via the WiFi network worked as expected as long as it was within the range of the access point. Testing was conducted with a maximum distance of 8 meters, as the WiFi access point device used in the experiment could only reach a maximum of 10 meters and operated at a frequency of 2.4 GHz. This shows that the system can function well within a certain range and supports efficient wireless data transfer.

Abstract

AbstractThis paper proposes moving horizon estimation (MHE) to estimate the state variables of autonomous vehicle linear systems under measurement noises. To solve the MHE optimization problem, quadratic programming is employed. The steering angle, yaw angle, and global position constraints of an autonomous vehicle are considered in the estimation design. According to the simulation results, it can be observed that although the longer MHE step can give better results compared to the shorter MHE step, the difference in the MHE step only slightly affects the estimated results. However, the longer MHE step can increase the computational time. Additionally, the proposed MHE scheme is compared to the Kalman filter (KF) estimator. Based on the obtained results, the KF gives a better estimation than the MHE, but this notion must be verified for other case studies.Keywords: autonomous vehicle; Kalman filter; linear system; MHE; quadratic programming. AbstrakPaper ini mengusulkan moving horizon estimation (MHE) untuk mengestimasi variabel keadaan sistem linier kendaraan otonom karena pengaruh noise pengukuran. Untuk menyelesaikan masalah optimasi MHE, digunakan pemrograman kuadratik. Kendala sudut kemudi, sudut yaw dan posisi global dari kendaraan otonom dipertimbangkan dalam desain estimasi. Dari hasil simulasi dapat diketahui bahwa meskipun langkah MHE yang lebih panjang dapat memberikan hasil yang lebih baik dibandingkan dengan langkah MHE yang lebih pendek, perbedaan langkah MHE hanya sedikit mempengaruhi hasil estimasi. Namun, langkah MHE yang semakin panjang dapat meningkatkan waktu komputasi. Selain itu, skema MHE yang diusulkan dibandingkan dengan estimator Kalman filter (KF). Berdasarkan hasil yang diperoleh, KF memberikan estimasi yang lebih baik daripada MHE, tetapi gagasan ini harus diverifikasi untuk studi kasus lainnya.Kata Kunci: kendaraan otonom; Kalman filter; sistem linier; MHE; pemrograman kuadratik. 2020MSC: 62P35, 65D19
