Comparison of BPA and LMA Methods for Takagi - Sugeno Type MIMO Neuro-Fuzzy Network to Forecast Electrical Load TIME Series

This paper describes an accelerated Backpropagation algorithm (BPA) that can be used to train the Takagi-Sugeno (TS) type multi-input multi-output (MIMO) neuro-fuzzy network efficiently. Also other method such as accelerated Levenberg-Marquardt algorithm (LMA) will be compared to BPA. The training algorithm is efficient in the sense that it can bring the performance index of the network, such as the sum squared error (SSE), Mean Squared Error (MSE), and also Root Mean Squared Error (RMSE), down to the desired error goal much faster than that the simple BPA or LMA. Finally, the above training algorithm is tested on neuro-fuzzy modeling and forecasting application of Electrical load time series

Wireless Data Logger with Microcontroller MCS-51

Nowadays, PLN has to hire employees to record the data which is shown by KWH meter at customer\u27s house. The employee can not record it if there are no people in customer\u27s house. To solve this problem, it is needed a KWH meter which can transmit data by using wireless data logger system, so that, the PLN\u27s employee can record the data although there are no people in customer\u27s house. This paper describes about implementation of wireless data logger system on KWH meter. Method used in this system is counting the rotation number of KWH meter plate, then microcontroller transfers the data to the remote device. The sensor used for counting the rotation number is infrared sensor as the transmitter and photodiode as the receiver. Experimental results show that the device can run well if the angle between remote and panel less than 40°, and the distance between remote and panel less than six meters. The maximum power consumtion of the device is not more than 5 watt

Desain Flux Vector Control Inverter 3 Fasa Pada Motor Induksi 1.5 HP Menggunakan Power Blockset

This paper describe Flux Vector Design Using Vector Matlab on 3 Phase Inverter when torque changes. Transient response is important things for inverter because it needs optimal torque that motor shows desire performance. This condition needs flux vector design that give V/F linear comparison in transient response. The experiment was done by simulating induction motor parameters using Matlab, the result shows : Torque supply 240 - 320 Nm, in 0.005 - 0.01s range of time

Identifikasi Gain Dan Bandwidth Audio Amplifier Menggunakan MCS-51

Like another commonly control-systems, audio amplifiersystem also has characteristics which are defined by their parametrics. Two of them are Gain and Bandwidth. An instrument for measuring Gain and Bandwidth can be built using microcontroller 89C51 from MCS-51 family dan programmed in assembly to generate its frequency (i.e. simulating VCO via software). This instrument use Digital to Analog Converter (DAC) type 0808, Analog to Digital Converter (ADC) type 0804, a Peak Detector Circuit, an Attenuator Circuit and a LCD. In this project, the constructed system can identify maximum Gain at 40 times with four-step increment and Bandwidth in the range from 10 Hz to 200 KHz. The system testing shows that the average error for Gain is less than 5% and approximately 10% for Bandwidth

Simulasi Sistem Penjadwalan Kereta: Studi Kasus Daop VIII Jawa Timur

Train rescheduling is often have to be made due to technical problems faced by the train that hold up the train to run on schedule or due to the addition of a new train. A simulation on train scheduling system can help out the train service company on rescheduling the train schedule. The simulation is made using Java language programming with queue rules that is usually used by the train service company. Based on the experiment on the system that was made on the overall class for the train rescheduling, 76 % of trains could have shorter trip time against the result of the simulation for GAPEKA (Grafik Perjalanan Kereta Api). The adjustment of train departure time is restricted to ± 30 minutes from the time regulated in GAPEK

Sistem Automasi Proses Produksi Minuman Dengan Sistem SCADA Menggunakan PLC

Industries need production processes that can be operated continually from one process to another without a lot of human energy resources. The solution of the problem is using an automation system which can be worked and operated from one central operator. SCADA with PLC can be used in many industrial processes because it can answer all the problems in controlling industrial application automatically. This paper describe how to make a design of simulation plant for beverages production process. The plant will use : pumps, mixer, valves, and heater. This plant will be operated by PLC Omron C-200 HS which is connected to SCADA Intouch, Wonderware Production. The comunication between PLC Omron and SCADA Intouch use Host Link RS 232c with I/O Servers program. The result from the simulation plant design for the minimum power shaft pump is 6.788 Watt. The mixer need a motor with speed 114 rpm. And the heater need 1000 Watt at 01:44:21.64. While the minimum valve design is needed to hold the fluids pressure until 106,4096 KPa
