In order to achieve the high precision and low computation, in this paper, we adopt well-known FAST (Features from Accelerated Segment Test) for feature detection and BRISK (Binary Robust Invariant Scalable Keypoints) for feature description. Then, we use Hamming distance and RANSAC (Random Sample Consensus) to match key points and estimate transformation parameters. To evaluate the performance of algorithms, three simulation experiments have been accomplished. The results and comparative analysis show a better performance of our proposed method.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133650814","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 difference between the state of the event-triggered system and that of the reference system, a Lyapunov-like function is defined to guarantee the boundedness of the tracking error. The proposed strategy reduces the amount of energy consumption and computation, thus results in less controller executions, and its feasibility is further verified by the exclusion of Zeno behavior.

In order to reduce the search scope, the region of parking apron is extracted by region growing based on OTSU segmentation. Moreover, Binarized Normed Gradient (BING) and Spectral Residual Saliency (SRS) are applied respectively to find useful proposals of potential aircraft targets with minor computing cost. Towards extracted proposals, the algorithm of Features from Accelerated Segment (FAST) is employed to locate key feature points precisely for various sizes of aircraft targets even very small ones. Then local invariant features characterized with well robustness against environment changes are constructed. Finally, the high speed detection algorithm of aircraft targets is implemented through adaptive matching of local invariant features with parameters adjustable accompanied by the size of aircraft targets. Comprehensive experiment results validate the well performance of our method with outstanding superiority in detection speed and accuracy for various sizes of aircraft targets.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"54 Suppl 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134547559","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}

To model the (partial, explicit) dependence of the players' payoff functions on the players' actions, an interference graph is introduced. Besides, the players are supposed to be equipped with a communication graph to achieve Nash equilibrium seeking in a distributed fashion. Nash equilibrium seeking strategy design is firstly explored under undirected graphs (including undirected interference graphs and communication graphs). In the proposed seeking strategy, each player generates estimates on the actions of its neighbors in the undirected interference graph. However, in some games, the payoff function of player j is a function of player i's action (i ≠ j), while the payoff function of player i is explicitly independent of the action of player j. To capture the asymmetric, explicit dependence of the players' payoff functions on the players' actions, Nash equilibrium seeking under directed graphs (i.e., directed interference graphs and communication graphs) is investigated. The seeking strategy under directed graphs further reduces the number of the estimation variables. The presented convergence results are analytically studied and verified by numerical examples.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134577626","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 controller is conducted by adopting global sliding mode which removes reaching phase and is shown to be globally asymptotic stable. To eliminate steady-state error and improve precision, disturbance observer is applied in the control strategy. Importantly, the value of controller parameters depends on a desired maximum velocity of spacecraft. Therefore the proposed controller can achieve speed limit at the same time without another controller. The behavior of the controller has been studied and analyzed. Numerical simulations are given in a flight dynamics scenario in which the spacecraft is asked to hover near asteroid Eros 433 to show the performance of the proposed controller.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133738413","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}

Tensegrity-like robots have received significant attention for its light-weight, robustness and deployability. However, the locomotion control of a tensegrity robot is still a challenging problem due to the complex nonlinear coupling among the struts and cables. In this paper, a straightforward, easy to implement compare-and-search based strategy for six-strut tensegrity robot is proposed to achieve continuous rolling toward given targets without developing step-wise locomotion policies for different adjacent relationship separately. To validate the proposed strategy, simulation experiments have been performed. Results show that the strategy works well on rough terrains and it is robust to external disturbances. In particular, the proposed strategy allows the robot to escape from the trap by jumping in certain situations. A physical prototype robot is also built based on the proposed strategy.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124818029","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}
