The confidentiality of information becomes an important thing because UAV hijacking occurs quite frequently. We develop an analog video transmission security for UAV with image encryption process by using Pseudo-Random Number Generator and assembling random image pieces with Linear Feedback Shift Register algorithm. The points to this security are the LFSR used as a seed that acts like a key to set the pattern of randomization from the images captured by the camera and processed by software on Raspberry Pi which is all mounted on UAV. The randomized image is sent using Analog Video Transmitter. The decryption is done on the ground station. The image result that received using a video receiver is decrypted using Raspberry Pi equipped with video grabber. In the experiment, we compared the similarity level between the original, scrambled, and decrypted images. It has 3.94 Percent similarity between original and scrambled images, 98.24 Percent similarity between original and decrypted images, and has 2.2 seconds latency.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A DC / AC converter, when the RS works in parallel with the distribution system, can also inject harmonics. The RS injection current’s value is fluctuating and unbalanced in the three phases due to irradiation changes. This condition causes the current that the transformer must supply by each phase is different. The instantaneous fundamental power demand, both active and reactive on the transformer at the PCC point, is also not the same. Likewise, when there are harmonics in the system. FLI is needed to inject or draw current on the PCC to balance the transformer’s current. The primary purpose of proposing this control system is to balance the current and eliminate the harmonic output current from the distribution transformer due to unbalanced RS injection capacity and unbalanced load. The proposed control strategy is to use single-phase PQ theory in controlling the FLI of each phase independently. The instantaneous power demand by the combined load and RS on the transformer is calculated and averaged. The result is evenly distributed across the transformers and FLI. Therefore, when viewed by the transformer, the load and RS become balanced even in unbalanced and fluctuating conditions. The simulation results with Matlab/Simulink, applying FLI with PQ Theory, improve the transformer’s current unbalance from 35% to 0.16%. THDi on phases A, B, and C decreased from 22.98%, 18.08%, 12.08% to 8.22%, 11.60%, 9.21%, respectively.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129212709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stroke is the number one cause of disability in the world and the number two cause of death in the world. Two thirds of strokes occur in developing countries. The most common effect in post-stroke conditions is weakening of the upper limbs or hemiparesis, which can be seen in 77% of people who recover. Weakening of the limbs causes the patient to not be able to control hand movements to the maximum so that it affects the ability of individuals to carry out daily activities, one of which is the ability of individuals to hold objects. A hybrid system device of functional electrical stimulation (FES) and soft-exoskeleton is developed. Multiple-Input-Multiple-Output Fuzzy Logic Controller (MIMO-FLC) is used as the control system. There are two inputs, two outputs, and 28 fuzzy rules from the FLC. It was found that the use of MIMO-FLC can integrate exoskeleton and FES better than MISO-FLC in previous studies. The control system using MIMO-FLC is an appropriate and effective method for integrating two different FES and exoskeleton actuation systems.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124233786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study discusses the SRM speed control as the main driving force for electric vehicles using linear approach. The SRM used in this paper has a narrow input saturation range. SRM only rotates at the PWM value of 72-84 or the equivalent input voltage to the SRM driver of 1.446 volts - 1.753 volts. At the PWM value of 0-71 and PWM 85-255, the SRM does not rotate (dead zone). This study discusses the design of SRM speed control with PI and PI Antiwindup (PI AW) methods in that narrow input saturation range. The design is done by modelling the system in the SysId MATLAB by looking at the SRM response when PWM input is given. A first-order dynamic model is obtained from the identification results with the SysId MATLAB. The controller design is carried out analytically. At the implementation stage, the control signal used is only a positive control signal that makes the motor rotate without any braking effect. The results of the implementation of PI and PI AW are compared to see the performance of the two controllers. From the simulation and implementation, data is obtained that the designed control system can control the SRM speed in reaching the steady state value, the overshoot value and the steady state error leading to 0%. PI AW controller has better performance than PI controllers in terms of settling time and overshoot percentage. The PI controller has a slight advantage at steady state error over the PI AW controller.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131696043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
