Power supply performance is an essential factor in determining the quality of, and is the basis for the proper functioning of various electronic devices. Thus, as a high-efficiency, high-reliability, and low-cost isolated DC/DC converter, the forward converter has been more and more widely used in industrial production and people's life. Therefore, it is of great market value and research significance to design a single-terminal forward converter. With the current PWM control chip UC3844 and high-frequency transformer as the core and the power MOS as the control switch, only simple peripheral circuits are required to enable the buck output. On this basis, the design of the input and output rectifier filter circuit, control circuit, driver circuit, and feedback compensation circuit module is completed.

Robot target tracking is a common application scenario for collaborative computing, which usually involves visual location, target analysis, route planning, attitude control and other task types with different computational complexities and real-time requirements. Given different computing capabilities, service loads, communication overheads, area crossing of different nodes at different time, the problem of how to allocate various services of the robot among the local, edge servers and cloud servers effectively according to the optimization objectives involves complex cloud edge cooperation strategy in the process of robot target tracking. To solve this problem, this paper proposes a cloud-edge collaborative framework for computing tasks based on load forecasting and resource adaptive allocation, which can efficiently allocate tasks of different types and complexities according to the current relative position of the robot with the servers, the computing resources and current loads of edge servers and cloud server. A large number of experiments show that this method can effectively shortens the average response time of various services and improves the service quality compared with traditional methods.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"333 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122846601","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}

In this paper, the distribution network is modeled as a tree and 0-1 array is used to represent the on-off between nodes. A flexible adaptive genetic algorithm is used to determine the islanded power restoration area. In the selection process, the improved pointer random sampling is used to replace the traditional roulette wheel sampling, and the flexibility in mutation is considered in order to improve individual fitness. Load recovery effect, network loss, and switching action cost are taken as objective functions to island areas optimally under the constraints of voltage, line capacity, network connection, and islanding capacity. The simulation results show that the proposed method can quickly form a recovery scheme and is feasible in power systems.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133795659","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}

As a result, the control accuracy deteriorates in application conditions with large temperature variations. In view of this situation, a temperature adaptive control strategy based on fuzzy PI is proposed. Firstly, the influence of temperature on the resistance, inductance and flux in PMSM is analyzed, and the mathematical model of PMSM is established in the two-phase rotating coordinate system; The parameter adjustment rules of fuzzy PI controller are designed in detail; The temperature adaptive control model of PMSM is built in Matlab / Simulink, and the control accuracy and robustness of the temperature adaptive control algorithm based on Fuzzy PI are verified by simulation. The experimental results show that, compared with the common PI controller, the temperature adaptive controller based on fuzzy PI can improve the dynamic performance and anti-disturbance performance of the system, and reduce the influence of temperature on the PMSM control performance.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124848189","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}

In the risk analysis process, the single fractal theory is mainly used to observe the characteristics of electricity price fluctuations, which ignores the seasonal characteristics of electricity price fluctuations, resulting in a sizeable average deviation of risk assessment results. Therefore, a new transaction risk assessment method based on multi-fractal theory is proposed. This paper analyzes the main links of electricity market transactions, defines the new electricity market transaction mode, and determines the source of transaction risks. Relying on the multi-fractal theory, this paper obtains the characteristics of electricity price fluctuation based on various influencing factors. It calculates the transaction risk value of the electricity market caused by electricity price fluctuation by combining the regression interval analysis method. The experimental results show that the average deviation of the risk assessment results calculated by the proposed method is 10.25 yuan (MW h)-1, which meets the risk assessment requirements. This method reflects the market risk and provides a basis for follow-up risk management.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123433604","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}
