This task becomes challenging as the starting point and ending points of the gestures are not usually obvious even for human being. This paper presents a method for continuous hand gesture recognition based on skeleton information that consists of two phases: gesture detection and gesture recognition. In our method, to leverage the lightweight and the robustness of recognition models, TD-Net (Triple Feature Double Motion) model is employed in both gesture detection and recognition phases. Experimental results on IPN dataset have shown that the proposed method outperforms different state-of-the-art methods with 40.10% of Levenshtein accuracy and 0.1ms of inference time.","PeriodicalId":273404,"journal":{"name":"2022 11th International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115723818","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}

Transient Over-voltages values are conducted by numerical simulation. Parametric studies using PSSE calculations and transfer in EMTP-ATP software are shown in this paper to simulate the worst-case fault locations inside the converter station to have the maximum value possibility of transient overvoltage.

At the second stage, detection results are obtained through the traditional one-stage detection network YOLOv5s.

The fuzzy logic controller has two inputs: speed and speed error, which are utilized by the SRM torque control loop. The 49-rule set also controls the FLC. The results show that the FLC reduces the motor's torque ripple more effectively than PI controllers. It makes the drive insensitive to parameter changes and compensates for the nonlinear torque characteristics of SRM. Additionally, the electromagnetic torque of the proposed FLC is more uniform than that of the conventional PI. The effectiveness of this FLC has also been demonstrated using MATLAB/SIMULINK simulation. Through simulation, the significance of this FLC technique has been shown.","PeriodicalId":273404,"journal":{"name":"2022 11th International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125337405","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}

However, their inherent uncertainties may lead to serious voltage deviations, load fluctuations and power losses. In this paper, we formulate a distributionally robust optimization (DRO) for vehicle-to-grid considering the uncertainties of solar power and PEVs. We utilize conditional value at risk to quantify the risk of violating inequalities containing uncertainties and the Wasserstein metric to reformulate the DRO problem into a tractable convex optimization problem. The DRO is implemented under a model predictive control framework to further reduce the uncertainties of PEVs and RESs. Numerical experiment results validate the efficiency of our method.","PeriodicalId":273404,"journal":{"name":"2022 11th International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128714380","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 order for soft-switching to achieve, the body diode of a MOSFET should conduct before the switch is triggered. This diode conduction occurs in the dead-time. If the dead-time is large, diode conduction loss may be significant that leads to the downgrade of system performance. This unwanted loss can be eliminated by triggering the MOSFET right at the instant when the transition completed. This paper proposed a method to detect that instant By using several low-cost passive components, a transition detection circuit can be built which can detect both the tura-on and turn-off transition completions. The effectiveness of the circuit is verified by simulation for DAB converter applications. However, it can also be used for detecting transition of other bridge-typed power electronic converter topologies.","PeriodicalId":273404,"journal":{"name":"2022 11th International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127535217","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 work, we equip a popular RL algorithm with two tools to improve exploration effectiveness and sample efficiency: the Episodic Noise, that helps useful subsets of actions emerge already in the first few training episodes, and the Difficulty Manager, that generates goals proportioned to the current agent’s capabilities. We demonstrate the effectiveness of such proposed tools on a pose regulation task of a four wheel steering four wheel driving robot, suitable for a wide range of industrial scenarios.

However, localization based on only a monocular camera or visual odometry is one of the most challenging research topics. Conventional methods are proposed based on the detection of key features in each image and matching them on consecutive images to estimate the camera motions. Deep-learning methods have also been studied to solve the problem. Although the current learning-based visual odometry methods score high results on public datasets, there is a lack of real-time implementation of the methods in common robot operating systems such as ROS to integrate them into a navigation system. In this paper, we introduce a ROS implementation of state-of-the-art conventional feature-based method, ORB-SLAM3, together with a deep-learning-based method, SC-SfMLearner for real-time UAV localization. A photo-realistic simulator, Flightmare, is used to test the implementation together with another navigation task such as control. The implementation can evaluate both algorithms in real-time operation to compare their performances. Based on evaluation results from the simulated environments, the limitation or failure cases of the algorithms could be found, then, the best parameters of the algorithms can be adjusted to improve the algorithms to avoid failures in practical experiments.","PeriodicalId":273404,"journal":{"name":"2022 11th International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124166274","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}
