Firstly, it operates in a static balancing mode, during which the controller tries to keep the pendulum balanced during which the controller tries to keep the pendulum balanced and maintain the current position of the pendulum carriage. Secondly, it also operates in a velocity control mode, so that the carriage can move at a selective velocity while simultaneously maintaining pendulum balance. In order to realize these two modes of control we implement a state feedback controller and schedule gain depending on the selected mode of operation of the system. We first describe the design and construction of the system. We then perform state space analysis, build state feedback controllers designed as linear quadratic regulators (LQR), and run tests to examine the operation of the system whilst subjecting the pendulum to impulsive disturbances. In particular, we investigate differences in control behavior in static position mode and in velocity-controlled mode. We present the experimental results and discuss their implications.","PeriodicalId":220599,"journal":{"name":"2022 International Conference on System Science and Engineering (ICSSE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127378574","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}

Since the outbreak of COVID-19, silent hypoxia has been one of the most serious symptoms. This symptom makes the patient’s SpO2 drop to an extremely low level without discomfort and causes medical care delay for many patients. Therefore, regularly checking our SpO2 has become a very important matter. Recent work has been looking for convenient and contact-free ways to measure SpO2 with cameras. However, most previous studies were not robust enough and didn’t evaluate their algorithms on the data with a wide SpO2 range. In this paper, we proposed a novel non-contact method to measure SpO2 by using the weighted K-nearest neighbors (KNN) algorithm. Five features extracted from the RGB traces, POS, and CHROM signals were used in the KNN model. Two datasets using different ways to lower the SpO2 were constructed for evaluating the performance. The first one was collected through the breath-holding experiment, which induces more motion noise and confuses the actual blood oxygen features. The second dataset was collected at Song Syue Lodge, which locates at an elevation of 3150 meters and has lower oxygen concentration in the atmosphere making the SpO2 drop between the range of 80% to 90% without the need of holding breath. The proposed method outperforms the benchmark algorithms on the leave-one-subject-out and cross-dataset validation.","PeriodicalId":220599,"journal":{"name":"2022 International Conference on System Science and Engineering (ICSSE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130802892","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 controlled system is a second-order analog circuit system. This second-order analog circuit system is implemented with an operational amplifier and has the transfer function characteristics of a second-order system. Many control systems can be reduced to the model of the second-order system, so the control implementation of this second-order analog circuit system has its applications. Genetic algorithms were originally developed from some phenomena in genetic biology, including inheritance, mutation, natural selection, and hybridization. The main control law is to use PID control, and the three parameters of the controller are adjusted by the genetic algorithm. This framework has the advantage of hierarchy, because the low-level control uses PID control, so it can ensure that the system is controllable. As for high-level parameter tuning, genetic algorithm are used to ensure optimal control.","PeriodicalId":220599,"journal":{"name":"2022 International Conference on System Science and Engineering (ICSSE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115574387","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 system uses tensorflow and keras and builds up a long short-term memory(LSTM) model to be able to predict the action which is being shown on the screen. We need to do is collect a bunch of data on all of our different key points, so we collect data on our face and save those as numpy arrays. The face detection method is based on a deep neural network using LSTM layers to go on ahead and predict that temporal component, which be able to predict action from a number of frames not just a single frame.

Different visual servo control methods are also discussed, including the Position-Based Visual Servo (PBVS), Image-Based Visual Servo (IBVS) and the proposed HVSC with the fuzzy dynamic control parameters. Characteristics of different visual servo control methods were discussed, and then applied to the actual harvesting.
