Abstract

This study proposes a Maximum Power Point Tracking (MPPT) method based on Particle Swarm Optimization (PSO) to enhance power extraction performance in Proton Exchange Membrane Fuel Cell (PEMFC) systems operating under dynamic and varying environmental conditions. The proposed method is designed to optimize the system's operating point to ensure that the power generated by the fuel cell is fully utilized. In this research, the PSO algorithm is integrated with an Interleaved Boost–Buck Converter (IBBC), which functions to reduce current ripple and improve the stability of the output power in the energy conversion system. This integration is expected to provide a faster and more efficient system response in adjusting to changes in operational conditions. One of the main challenges in implementing MPPT in PEMFC-based systems is the nonlinear characteristics of PEMFC itself, which are highly influenced by various external parameters such as operating temperature, hydrogen pressure, and membrane water content. Variations in these parameters can cause fluctuations in output voltage and current, making the maximum power point tracking process more complex. Therefore, an adaptive optimization method with good convergence ability is required. Simulation results demonstrate that the proposed PSO method achieves a tracking accuracy of up to 99.96% with a settling time of 2 seconds under varying membrane water content conditions. The PSO approach also outperforms the Fuzzy Logic and Cuckoo Search Algorithm (CSA) methods. These findings confirm that the integration of PSO and IBBC significantly improves both the accuracy and speed of MPP tracking in PEMFC systems.

Abstract

Voltage control in DC–DC converters, especially buck converters, is a crucial element in modern power electronics systems because it directly impacts the efficiency, stability, and quality of supply in low- to medium-power electronic devices and industrial applications. Recent studies have emphasized that the nonlinear and load-dependent dynamics of converters require control strategies capable of maintaining stability despite parameter variations and external disturbances. PID-based control methods remain the most widely used approach due to their ease of implementation and ability to handle transient responses, although improper parameter tuning often leads to overshoot and slow response in power converter systems. This challenge is increasingly apparent in buck converters, which have fast dynamics and high sensitivity to load changes, making conventional tuning sometimes inadequate. Internal Model Control (IMC) is one of the modern tuning methods that offers a solution due to its model-based approach and its ability to produce control parameters that are more robust to system uncertainty. This study specifically analyzes the application of the IMC-PID method in buck converters by utilizing the FOPDT model to obtain the , , and  parameters. This approach is expected to provide more stable, faster, and adaptive tuning results compared to conventional methods. Keywords: IMC, PID, buck converter, voltage control.

Abstract

Penelitian ini bertujuan untuk menganalisis respon dinamis buck-boost converter terhadap variasiduty cycle dan perubahan beban. Buck-boost converter merupakan salah satu jenis konverter DC–DC yangmampu menghasilkan tegangan keluaran lebih tinggi maupun lebih rendah dari tegangan masukan melaluipengaturan nilai duty cycle. Pada penelitian ini, fokus analisis diarahkan pada dua aspek utama, yaituperubahan duty cycle sebagai parameter kontrol dan variasi beban sebagai kondisi operasional yangmemengaruhi karakteristik keluaran sistem.Pengujian dilakukan dengan menerapkan beberapa nilai duty cycle untuk mengamati perubahantegangan keluaran serta respon transien yang muncul, meliputi ripple tegangan, overshoot, undershoot, risetime, dan settling time. Selain itu, variasi beban diterapkan untuk mengevaluasi stabilitas dan kemampuankonverter mempertahankan performa dinamis pada kondisi beban ringan, sedang, dan berat. Data keluarandiperoleh melalui pengukuran langsung menggunakan perangkat akuisisi sinyal dan dianalisis untukmengetahui hubungan antara parameter kontrol dan karakteristik dinamis konverter.Hasil penelitian menunjukkan bahwa peningkatan duty cycle secara umum menghasilkan kenaikantegangan keluaran, namun juga berdampak pada perubahan respon transien, terutama pada kondisi bebanberat. Sementara itu, variasi beban berpengaruh signifikan terhadap kestabilan tegangan keluaran dan nilairipple. Kesimpulan utama menyatakan bahwa baik duty cycle maupun beban memiliki peran penting dalammenentukan performa dinamis buck-boost converter, sehingga keduanya harus dipertimbangkan dalamperancangan sistem konversi daya yang stabil dan responsif.

Abstract

The impeller wheel is an important component of centrifugal pumps, which need to get importantattention starting from designing and modeling impeller shapes. This is very influential on theperformance of the pump. This study aims to determine the exact model of the impeller in theinstaller in parallel and to maintain the balance of the pump working operation with time. Themethod used is a comparative system of pump impeller models in order to improve pumpperformance optimally. From the results of this study that the pump with a discharge of 3.1 m3/sobtained optimum results with a pump head of 281 meters and an efficiency of 88% and dimensionsof the blade width of 22.5 cm for the double suction pump type.
