"Jaringan Saraf Tiruan adalah salah satu metode baru yang dikembangkan untuk pemecahan berbagai masalah kompleks yang tidak dapat diselesaikan secara analitik. Salah satu pengembangannya adalah metode jaringan saraf pembelajaran Radial Basis Function, dengan metode inisialisasi bobot Nguyen-Widrow dan Orthogonal Least Square (OLS). Akurasi dan kecepatan pembelajaran yang dimiliki oleh Radial Basis Function (RBF) sangat menarik untuk diaplikasikan pada sistem kendali. Pemodelan Forward dan Invers sistem dilakukan dengan metode RBF dengan mengambil data sistem SISO Pressure Process Rig. Setelah dilakukan pemodelan, jaringan saraf tiruan akan diuji dengan Direct Inverse Test. Hasil identifikasi sistem dan identifikasi invers pada sistem Pressure Process Rig memiliki hasil yang baik. Begitu pula saat diuji coba dengan Direct Inverse Test, sistem kendali mempunyai performa cukup baik, namun tidak menutup kemungkinan adanya skema model lain yang dapat digunakan dalam pemodelan sistem.

Artificial Neural Network is a newer field of study that could solve any complex problem that could not be done by analytical solution. Radial Basis Function (RBF) is one of the newer method of Artificial Neural Network with two distinct weight initialization method ; Nguyen-Widrow and Orthogonal Least Square (OLS) methods. RBF?s high recognition rate and very fast learning speed are interesting enough to be used in control system. RBF is used in forward and inverse identification in modelling Pressure Process Rig system. Direct Inverse Test is also done in order to make sure Radial Basis Function perform well in identifying a particular system. Radial Basis Function had a great perfomance in both forward and inverse system identification and also in Direct Inverse Test, but it is possible to have another learning scheme in system modelling."

"[ABSTRAKPerkembangan teknologi yang semakin cepat menjadikan teknologi penting di berbagai sektor kehidupan, khususnya di bidang industri. Perkembangan zaman membuat tingkat permintaan akan suatu produk menjadi berubah sehingga industri harus meningkatkan kinerja produksinya.Teknologi yang digunakan merupakan teknologi automasi di mana di dalamnya terdapat pengendali. Pengendali yang digunakan oleh kebanyakan industri merupakan pengendali konvensional karena pengendali konvensional relatif murah dan efektif. Akan tetapi pengendali konvensional ini tidak dapat digunakan untuk sistem yang kompleks dan non linear. Pengendali konvensional, misalnya pengendali PID, tidak dapat mengatasi terjadinya perubahan karakteristik dari sistem secara otomatis. Untuk itu diperlukan sistem pengendali yang mampu mengatasi perubahan karakteristik secara otomatis dan dapat beradaptasi dengan dinamika perubahan sistem yang diakibatkan adanya perubahan kondisi lingkungan kerja. Sistem pengendali yang dianggap mampu untuk beradaptasi dengan perubahan karakteristik dari sistem secara otomatis adalah pengendali berbasis Neural Network. Dalam percobaan ini parameter yang digunakan untuk menentukan pengendali yang baik adalah adaptivity serta kecepatan respon pengendali.Pada hasil simulasi ini didapatkan bahwa pengendali berbasis Neural Network dengan metode Radial Basis Function Neural Network (RBFNN) lebih baik dan lebih cepat dalam menanggapi perubahan karakteristik sistem dibandingkan dengan pengendali Neural Network berbasis backpropagation.ABSTRACTDevelopment of technology has been rapidly increasing that make technology as an important aspect in many sectors of life, especially in industrial sector.

Perkembangan kecerdasan buatan (artificial intelligence/AI) bergerak semakin cepat dan mengalami kemajuan pesat dalam setiap bidang kehidupan manusia, tak terkecuali dalam dunia kendali industri. Sementara kendali industri mensyaratkan sistem pengendali yang mampu mengatasi perubahan karakteristik secara otomatis serta dapat beradaptasi dengan dinamika perubahan sistem yang diakibatkan adanya perubahan kondisi lingkungan kerja. Pengendali berbasis kecerdasan buatan dianggap mampu untuk beradaptasi dengan perubahan karakteristik dari sistem secara otomatis adalah pengendali berbasis neural network. Dalam penelitian ini disajikan desain dan simulasi sistem pengendali berbasis neural network dengan metode pembelajaran back propagation yaitu pengendali inverse langsung(direct inverse control/DIC), pengendali neuron tunggal(single neuron controller), serta pengendali PID pada plant modul training pressure process rig(PPR 38-417). Untuk pengujiannya, didesain sistem identifikasi berbasis neural network sebagai simulator plant. Hasilnya, semua sistem kendali yang didesain tersebut mampu mengendalikan plant sesuai dengan sinyal referensi yang dinginkan. Namun pengendali single neuron dan PID mampu mempertahankan keluarannya dengan baik saat diberi gangguan pada sinyal kendali maupun plant dibandingkan dengan pengendali inverse langsung(ANN-DIC). Hal ini dikarenakan kendali single neuron dan PID bersifat close loop sehingga mampu mengkoreksi kesalahan secara langsung. Sementara jika dibandingkan dengan kendali PID, kendali single neuron lebih adaptif untuk berbagai kondisi gangguan karena memiliki metode pembelajaran langsung, sementara kendali PID perlu dilakukan tunning untuk mendapatkan unjuk kerja yang handal.

The development of artificial intelligence (AI) is moving faster and experiencing rapid progress in every area of human life, not least in the world of industrial control. While industrial control requires a control system that is able to overcome changes in characteristics automatically and can adapt to the dynamics of system changes caused by changes in working environment conditions. Artificial intelligence-based controllers are considered capable of adapting to changes in the characteristics of the system automatically is a neural network-based controller. In this study, the design and simulation of a neural network-based controller system with back propagation learning methods, namely direct inverse control (DIC) and single neuron controller, as well as PID controllers for the pressure process rig (PPR 38-417) training module. For the test, a neural network-based identification system is designed as a simulator plant. As a result, all the control systems designed are able to control the plant in accordance with the desired reference signal. However, single neuron and PID controllers are able to maintain their output well when given interference with the control signal or plant compared to the direct inverse controller (ANN-DIC). This is because single neuron control and PID are close loop so that they can correct errors directly. Meanwhile, when compared to PID control, single neuron control is more adaptive for a variety of disruption conditions because it has a direct learning method, while PID control needs to be tuned to get reliable performance.
