Brain activity can properly reflect physical and mental status of subjects during prolonged exercise, and long-term exercise may affect the power spectrum of EEG. Many studies showed that ECG, EMG and EEG, can effectively and accurately assess the status change during exercise. Safety and efficiency are the main concerns for promoting the aerobics for the elder. In this study, we aim to investigate the EEG and ECG features that can reveal status change during cycling exercise. Twenty-nine healthy subjects participated in this study. After four-minute resting stage, participants were asked to take cycling exercise continuously for twenty minutes, and the EEG, ECG signals were recorded and analyzed. The EEG data were divided into one-minute epoch and the wavelet transform was used to analyze five frequency bands, namely, theta (T), low alpha (LA), high alpha (HA), low beta (LB) and high beta (HB). The ECG signal was used to establish the average maximum heart rate ratio (AMHRR) and cardiac stress index (CSI). We found variations of RR intervals decreases during sustained cycling exercise. The CSI plot of a less frequent exerciser showed steeper than a frequent exerciser. If a participant has a steeper slope of CSI curve may imply an increase in cardiac stress. The AMHRR score at 65% could be a threshold for the occurrence of feeling hard during exercise. The CSI, HA and LB are the most proper features for assessing status change during exercise.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126630596","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}

Based on the neural network (NN)-based adaptive dynamic programming and Lyapunov-Razumikhin theorems, the robust control design problem can be equivalently transformed into a nearly optimal control problem, and the amount of matched uncertainties are indirectly reflected in the performance index. A nearly optimal control is designed to approximate the costate function of the Hamilton-Jacobi-Isaaca (HJI) equation by NN-based adaptive dynamic programming scheme. By algebraic inequalities and appropriate uncertainty descriptions, sufficient conditions are derived under which not only the uncertain input-delay dynamical systems can achieve asymptotic stability, but also acquire the guaranteed level of performance for regulation. Simulation example is performed to demonstrate the effectiveness of the proposed approaches.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133142917","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 proposed system consists of monitoring and controlling parts. We use an Arduino Uno Wi-Fi board to be the platform and 4 PIR sensors for four partitions to detect intruders. When the 4-PIR sensor module detects someone close to the system, the buzzer will play alarm sounds and the servo motor will turn to specific angles to track the nearest intruder, at the same time the webcam will screenshot due to motion detection, and the system will email the screenshot pictures to users and backup these pictures in a cloud storage system. After receiving the mailed message, users can decide whether turn on the live-stream function via their mobile phones or computers. Moreover, once users turn on the live-stream via the developed APP, they can click a screenshot button to screenshot the APP screen. And the picture will also be saved in users’ mobile phones. In addition, users are allowed to remotely control some devices of the system via mobile phone APP to further monitor.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116884251","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}

Al-Talabi","doi":"10.1109/CACS.2017.8284272","DOIUrl":"https://doi.org/10.1109/CACS.2017.8284272","url":null,"abstract":"This paper proposes a fuzzy reinforcement learning technique that enables a group of pursuers in pursuit-evasion (PE) differential games to learn how to capture a single superior evader in a decentralized manner. The superiority of the evader is in term of its maximum speed which means that this speed exceeds the maximum speed of the fastest pursuer in the game. The proposed learning technique uses a fuzzy actor-critic learning Automaton (FACLA) algorithm together with the so-called Apollonius circle technique and a specific formation control strategy which are used to define the necessary reward function for each pursuer. This enables each pursuer to update its value function accurately. Accordingly, the pursuer will take the right actions by tuning its fuzzy logic controller (FLC) parameters. The formation control strategy is also used such that during the capturing process the distribution angles of the pursuers around the evader are invariant as much as possible. Furthermore, it is also used to avoid a collision among them. It is assumed that the superior evader is an intelligent evader whose strategy is to continuously search for a gap during the evasion process by using the Apollonius circle method. If there is a gap, the evader will select its path through the gap to escape otherwise the evader will change its direction to increase the capture time. Simulation results are given to validate the proposed learning algorithm.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114604410","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 zero-power magnetic suspension has been applied to vibration isolation system because it has a negative-stiffness property. High stiffness against direct disturbance on the isolation table can be achieved by combining it with a normal spring with a positive stiffness. It enables the system to have good characteristics in both the performances of isolation from ground and suppression of direct vibration. However, the vibration isolation system using zero-power magnetic suspension has several problems. One of them is that a large/strong permanent magnet is necessary to support the isolation table. Another problem is a technical difficulty of achieving sufficient damping for suppressing resonance. It is proposed to insert elastic ferromagnetic substance between the magnet for suspension and the object to be suspended. Since it decreases magnetic reluctance, the suspension force increase. In addition, the damping characteristics of the suspension system is improved by the elasticity of the substance.","PeriodicalId":185753,"journal":{"name":"2017 International Automatic Control Conference (CACS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130636013","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}
