Abstract

In controlling permanent magnet synchronous motor (PMSM) without using a rotation sensor (sensorless control), some motor parameter data is needed. Among the motor parameters used in the control are stator resistance, inductance, and magnetic flux. This paper will analyze the effect of these parameter values ​​in sensorless motor control. The parameter values ​​will be varied so that the motor parameter values ​​in the controller are different from the actual motor parameter values. The percentage of variation for each parameter varies depending on the influence of these parameters on control. The desired motor speed is 100 rad / second with controlling constants KP = 0.5, KI = 0.9, and KD = 100. The controller gain values ​​(KP, KI, and KD) are obtained by the heuristic tuning method. Simulations are carried out for several differences in parameter values ​​using Simulink. From the simulation results, it is found that the motor parameter values ​​of the controller that are not the same as the actual motor parameter values ​​will affect the control process. The difference in the motor parameter value between the controller and the actual value causes the motor not to rotate as the desired value.

Abstract

This paper discusses the design of Ultra-Wideband (UWB) hexagonal monopole planar microstrip antenna with bandwidth enhancement characteristic using hexagonal shaped slot ring EBG and triple notch-band characteristic using three different slots. A hexagonal shaped monopole planar antenna is integrated with an EBG structure in order for the antenna to work at 2,8 -16 GHz bandwidth. A combination of L shaped, horizontal, and round shaped slots with different length are also integrated in the patch to remove three frequency band at WLAN (4,9-6,2 GHz), satellite downlink communication (7,1-7,6 GHz), and Direct Broadcasting Satellite (DBS) (12,2-12,7 GHz). The overall dimension of the antenna is 35,6 mm x 27,3 mm, with a thickness of 1,6 mm. The final design of the antenna shows a good result at frequency band 2,86-16,08 GHz under the reflection coefficient < -10 dB, except at frequency WLAN (5,5 GHz), X-Band satellite (7,45 GHz), and DBS service (12,45 GHz), with maximum gain of 4,8 dBi at 14 GHz, and good antenna efficiency ranged from 45% to 85%.

Abstract

Changes in temperature can affect the accuracy of the estimated SoC value based on voltage. In this study, fuzzy logic was implemented to correct the SoC estimation error caused by the influence of temperature. The system acquired data through sensors and then processed it using the Arduino microcontroller. Parameters in the form of voltage, temperature, and current were processed by Arduino with a fuzzy logic program which was uploaded into it and produced the output of the estimated SoC value. From the observations, it was found that the estimated SoC value from this method had better accuracy with a smaller error than the SoC estimation based on voltage alone. Using the RMSE method, the errors calculated in this method in the process of charging and discharging without running were 2.26 and 7.74, while the SoC estimation error based on voltage alone reached 4.88 and 12.8. In the discharging process with a running car, the SoC estimation results using fuzzy logic also showed accurate results. There was only 1% of SoC value increasing pattern during the discharging process, which the value trend should continue to decrease and should not be an increase. In addition, compared to the previous method applied to the same research object, namely the chemical equilibrium constant method, this method also showed more accurate results.

Abstract

This study is aimed to improve the performance of a short essay scoring system. The improvement is executed by integrating a simple linear regression to the output of a combined cosine similarity method (with weighted term frequency using Term Frequency –Inverse Document Frequency (TF-IDF) method) and term-matching mechanism.The linear regression is conducted by taking the short essay score (resulting from the combined cosine similarity and termmatching) as a regressor variable. In order to demonstrate the effectivenessof the proposedscoring system, the performance of the scoring system is measured relative to manual scoring by a lecturer.The results show that prior to linear regression, the scoring system tends to give higher score(biased score) compared to the manual score,which is problematic. The following scoring system with linear regression tackles this problem as the scoring bias is significantly reduced, that is, no tendency to givehigher or less scorecompared to the manual score.That the scoring bias is significantly reduced using a simple approach, linear regression,is expected to contribute in the acceleration of implementingautomatedessay scoring system on online learning technologiessuch as e-learning.
