To achieve tight output voltage regulation in the presence of various disturbances, DC-DC converters incorporate a control strategy to regulate power flow and power level. In recent times, several control strategies have been investigated for regulating the action of DC-DC converters, ranging from the conventional frequency domain to time domain design approaches. However, not enough attention is given to the performance of the state feedback controller, especially during rapid load current change in dc-dc converter. In this paper, a full order state-feedback controller was designed, and the performance was investigated for rapid load current change. A state feedback controller was first designed in this work, and then the integrator is introduced to eliminate the inherent steady-state error for improved system robustness to disturbance rejection. The state feedback controller performance was evaluated by subjecting the converter to various step load current changes in which the controller rejected the disturbance faster when compared with the PID controller used as a base controller. The fast transient response will allow the DC-DC converter to accept wider current change from rapidly changing loads and achieve improved output voltage regulation.","PeriodicalId":386462,"journal":{"name":"2022 International Conference on Future Trends in Smart Communities (ICFTSC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123937617","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}

It is a single-stage AC-AC power converter that can produce variable output frequency from constant input frequency and, at the same time, it can control the magnitude of the output voltage. However, a high number of harmonics component is generated by the cycloconverter because of its non-sinusoidal outputs which affects the performance of the load. The experimental harmonic analysis for any cyclo-converter at 230V AC is hardly found in the literature. Hence, this paper presents the harmonic analysis of the outputs of a IGBT based cyclo-inverter circuit for 100 Hz, 150 Hz, and 200 Hz operation. THD of the output voltage and current are investigated through MATLAB/ Simulink simulation and experimental analysis at 230V AC systems.","PeriodicalId":386462,"journal":{"name":"2022 International Conference on Future Trends in Smart Communities (ICFTSC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123174921","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}

IoT devices are commonly powered by batteries especially in areas where there are no electrical sources. However, these batteries have limited capacity and will eventually be depleted, which affects the lifetime of the IoT applications. The replacement of batteries are time consuming and incures additional costs. Therefore, energy saving schemes are needed to prolong the lifetime of IoT applications. This paper proposes energy saving schemes at the sensor nodes using two methods, that are low power method and shutdown and wake up method. In the former, a low-power microcontroller that uses low voltage is chosen, its low power mode puts the board to sleep and its unused peripherals are turned off during idle periods. In the latter, a Real Time Clock (RTC) module and a P-Channel MOSFET is used to to wake the microcontroller board at certain time interval, to further reduce the power consumption. A suitable low power wireless communication protocol, Zigbee, is also used for sending data between the sensor node and sink node. The current consumptions of the system are captured by a power measurement module. Experimental results show that the low power and shutdown and wake up methods can provide energy savings of 83.70% and 96.51%, respectively. The implementation of energy saving schemes is vital to ensure extended lifetime of IoT applications.","PeriodicalId":386462,"journal":{"name":"2022 International Conference on Future Trends in Smart Communities (ICFTSC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117105535","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}

Despite widespread recognition of their importance in determining the performance of an object re-ID model, not enough attention is paid to how these factors affect re-ID systems. One of the major impediments to investigating how these factors affect the performance of re-ID models is the lack of datasets with unbiased distribution of these difficult visual conditions. To make up for the lack of large-scale datasets with a balanced distribution of such photometric and geometric transforms, recent studies suggest using game engines to generate synthetic datasets. This study proposes a quantitative investigation of the impact of two critical visual factors: illumination and Tranfomer-based re-ID models on synthetic dataset.","PeriodicalId":386462,"journal":{"name":"2022 International Conference on Future Trends in Smart Communities (ICFTSC)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114410090","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}

The parameters of the circulator are designed and simulated by ANSYS High-Frequency Electromagnetic Simulation (HFSS) software. Isolation is one of the key indicators of the circulator’s performance. The simulation results show that an isolation of the circulator in the mid-band range of 3.3-3.8 GHz is greater than 22 dB, and the relative bandwidth exceeds 14%, which is sufficient for 5G spectrum n78. In addition, the return loss when port 1 excited is greater than 20 dB in the working frequency band. The relationship between uniform and non-uniform biasing simulations, ferrite and dielectric material selection are the main important point to considered for designing high isolation circulator. Therefore, the circulator presented in this paper can provide a reference scheme for the design of high-performance circulator or isolator.","PeriodicalId":386462,"journal":{"name":"2022 International Conference on Future Trends in Smart Communities (ICFTSC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116024975","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}
