Abstract

This paper describes about development of sensorless control for three phase induction motor speed which is operated by Direct Torque Control (DTC). Induction motor speed is identified by an Observer. Current supply and Stator Voltage are ruquired by Observer to gain Motor Speed Estimation. Observer for motor speed identification is developed using Artificial Neural Network (ANN) Method and Recurrent Neural Network (RNN) learning algorithm. The simulation results using MathLab/Simulink show that on PI controller with Recurrent Neural Network (RNN) observer, there are the overshoot 7,0224%, rise time 0,0125 second and settling time 0,364 second with reference speed 77,9743 rad./sec.

Kecepatan motor induksi diidentifikasi oleh suatu observer. Estimasi kecepatan motor oleh observer memerlukan masukkan arus dan tegangan stator. Observer untuk identifikasi kecepatan motor menggunakan metode Artificial Neural Network (ANN) dengan algoritma pembelajaran menggunakan Recurrent Neural Network (RNN). Hasil simulasi menggunakan matlab-simulink menunjukkan saat motor diberikan kecepatan referensi 77,9743 rad/detik terjadi overshoot 7,0224% , rise time 0,0125 detik dan settling time 0,364 detik.

Abstract

This paper describes about development of 3 phase speed sensorless induction motor speed controller using Field Oriented Vector(FOC) method. Motor speed is estimated by an observer using Self Constructing fuzzy Neural Network (SCFNN) with Levenberg Marquardt(LM) learning algorithm method, that replaces backpropagation method because this method is slow to reach convergent. SCFNN method combines the fuzzy and neural network. The simulation results show that the system can estimate flux and speed of induction motor and it converges faster than backpropagation method. .The estimation result can be used to identify rotor speed of induction motor with good performance Abstract in Bahasa Indonesia: Dalam penelitian ini dikembangkan pengaturan kecepatan motor induksi 3 phase tanpa sensor yang dioperasikan dengan metoda Field Oriented Vector (FOC). Kecepatan motor diestimasi oleh suatu observer dengan suatu metoda Self Constructing Fuzzy Neural Network (SCFNN) dimana pelatihannya menggunakan metode algoritma pelatihan Levenberg Marquardt (LM), yang menggantikan metode Backpropagasi karena metode ini kurang cepat mencapai konvergen. Metode SCFNN mempunyai kemampuan untuk menggabungkan Fuzzy dan Neural Networks. Hasil simulasi menunjukkan sistem dapat mengestimasi fluksi dan kecepatan dengan kekonvergenan yang lebih cepat dari metode backpropagasi. Hasil estimasi dapat digunakan untuk mengidentifikasi kecepatan rotor motor induksi Kata kunci: pengaturan kecepatan, motor induksi tanpa sensor, FOC, SCFNN observer, Levenberg Marquardt

Abstract

This research develops the settlement mechanism in the Real Time Gross Settlement using so called clearing house through a serious game method. In this approach banks are represented as nodes that do the settlement process according to the simple rules. Moreover, the graph mining approach is used for predicting the activity networks on those banks. As the result, for constant nodes indicate that the more the activity networks among banks are available, the more the activity networks can be identified. Furthermore, the smaller the differences among the bank health’s level are, the greater the network activities can be identified. This behavior is a consequence of chosen fixed point assumption.

Abstract

The development of Inverter Fuzzy Logic Control for Induction Motor Control by Vector Control Method in Electric Vehicle. In response to concerns about energy cost, energy dependence, and environmental damage, a rekindling of interest in electric vehicles (EV’s) has been obvious. Thus, the development of power electronics technology for EV’s will take an accelerated pace to fulfill the market needs, regarding with the problem in this paper is presented development of fuzzy logic inverter in induction motor control for electric vehicle propulsion. The Fuzzy logic inverter is developed in this system to directed toward developing an improved propulsion system for electric vehicles applications, the fuzzy logic controller is used for switching process. This paper is describes the design concepts, configuration, controller for inverter fuzzy logic and drive system is developed for this high-performance electric vehicle.
