"Isu tentang Energy Harvesting  saat ini sedang marak dikembangkan oleh banyak peneliti. Salah satu device Energy Harvesting  yang saat ini sedang berkembang adalah device Hygroelectric Generator  (HEG). HEG adalah device yang bisa mengkonversi energi potensial molekul air yang berbentuk uap yang terkandung dalam kelembaban menjadi energi listrik. Pengembangan HEG juga mendorong perlunya pemodelan device HEG. Ketika HEG masuk fase komersil nantinya, maka model matematika device HEG sangat diperlukan. Pada penelitian ini sudah dilakukan rancang bangun sistem akuisisi data device HEG yang bisa mengukur tegangan keluaran device HEG di mana tegangan tersebut dipengaruhi oleh kondisi suhu dan RH lingkungannya. Data hasil akuisisi tersebut juga sudah digunakan lebih lanjut untuk mencari model matematika device HEG dengan metode identifikasi sistem menggunakan model struktur nonlinier ARX di mana metode estimasi parameternya menggunakan Levenberg-Marquardt. Hasil model terbaik yang dapat dicari dengan parameter λ terbaik yaitu 0.1 adalah model nonlinier ARX dengan satu network sigmoid dan menghasilkan MSE 0.055159 , AIC -18093.74221 serta parameter sebanyak 63. 

The issue of Energy Harvesting  is currently being widely developed by many researchers. One of the Energy Harvesting  devices that is currently being developed is the Hygroelectric Generator  (HEG). HEG is a device that can convert the potential energy of water molecules in the form of vapor contained in humidity into electrical energy. The development of HEG also necessitates the modeling of HEG device. When HEG enters the commercial phase in the future, a mathematical model of the HEG device will be highly necessary. In this research, the design and construction of an HEG device data acquisition system has been carried out which can measure the output voltage of HEG devices where the voltage is affected by the temperature and RH conditions of the environment. The measurement data obtained has also been further used to find a mathematical model of the HEG device using the system identification method with a nonlinear ARX structure model, and the parameter estimation method using Levenberg-Marquardt. The best model obtained with the optimal parameter λ of 0.1 is a nonlinear ARX model with one sigmoid network, resulting in an MSE of 0.055159, AIC of -18093.74221, and a total of 63 parameters."

"Penelitian ini akan mengembangkan pengendali MIMO Model Predictive Control (MPC) dengan constraints serta ditambahkannya fungsi Laguerre. Metode ini akan diterapkan pada sistem tata udara presisi atau biasa disebut sistem Precision Air Conditioning (PAC) dengan dua masukan, yaitu putaran kipas dan kompresor, dan dua keluaran, yaitu temperatur dan kelembapan relatif. Permasalahan yang ada pada proses kendali PAC ini ialah tetap menjaga temperatur dan kelembaban dari suatu sistem refrigasi sesuai dengan yang hasil yang diinginkan, yaitu pada temperatur 20-25 oC dan kelembaban relatif 40-55%. Penelitian ini adalah pengembangan dari penelitian sebelumnya yang tidak bisa mengendalikan sistem PAC dengan hasil yang memuaskan. Metode identifikasi yang digunakan menggunakan metode PO-MOESP untuk mencari model A, B, C, D dan menjadi masukan pengendali prediktif. Fungsi Laguerre ditambahkan untuk mengurangi waktu komputasi ke dalam MPC. Penelitian ini menggunakan software Matlab untuk melakukan proses simulasinya. Hasil keluaran pengendali MPC constraints biasa akan dibandingkan dengan pengendali MPC constraints dengan fungsi Laguerre.

This research will aim to develop MIMO Model Predictive Control (MPC) controller with constraints added with Laguerre function. This method will be applied to Precision Air Condition (PAC) system with two inputs : fan and compressor speed; and two outputs : temperature and humidity. The problem in this PAC control process is to maintain temperature and humidity of the refrigeration system as desired, which is temperature 20-25oC and relative humidity 40-55 %. This research is developed from previous research, which could not control PAC system with feasible result. System identification used in this research is PO-MOESP method to find A, B, C, D model as input for predictive controller process. Laguerre Function was added for reducing computation time into MPC Controller. This research use MatLab software to run the process simulation model. Output of the conventional MPC controller with constraints will be compared to MPC controller with constraints and Laguerre function."

"The book serves as a unique integrated platform, which not only describes the design methodology of electro-hydraulic actuation systems but also provides insights into the design of the servo valve, which is the most important component in the system. It presents a step-by-step design process, comparative tables, illustrative figures, and detailed explanations. The book focuses on the design and testing of electro-hydraulic actuation systems, which are increasingly being used in motion control applications, particularly in those where precision actuation at high operational rates is of prime importance. It describes in detail the design philosophy of such high-performance systems, presenting a system used as a physical test setup together with experimental results to corroborate the calculations. Of particular interest are the electro-hydraulic servo valves that form the heart of these actuations. These valves are complex and not much data is available in open literature due to OEM propriety issues. In this context, the book discusses the elaborate mathematical models that have been derived and an approach to validate the mathematical models with test results. Presenting the complex methodology in simple language, it will prove to be a valuable resource for students, researchers, and professional engineers alike."
