Fuzzy control is developed to make the robots move in the predefined trajectories that must not collide.

The simulation results obtained with three mobile robots are presented to show the performance of control, coordination and crash avoidance algorithm.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134433305","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 first one is based on sliding mode observers. The principle is to reconstruct the state vector and the outputs of the system by sliding mode observers and to compare the estimated outputs with those measured, the obtained difference is considered as residual. The second approach rests on nonlinear analytical redundancy (NLAR) and consists to eliminate the unknown states and variables in order to obtain relations where all variables are known. The objective of this paper is to show the interest of the two approaches for detecting sensor or actuator faults of autonomous electric vehicle. Simulation results show that the method of NLAR is more adequate to detect actuator faults and the sliding mode observer is better for detecting sensor faults.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117180066","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 threshold sampling scheme selects the coefficients above a predefined threshold, while, zonal sampling scheme selects the coefficients inside a predefined geometric zone. In this paper, a new scheme for the zone construction of the selected coefficients is presented, in this procedure, the higher-value coefficients are selected using a mathematical formulation. The experimental results, using a group of transforms are compared with that of the other two sampling schemes employing the same transforms. The comparison demonstrates the effectiveness of this method.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120977062","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 methodology is based to adding a noise cluster to clustering algorithm. The proposed approach allows the identification of the premise parameters and the consequence parameters together via iterative minimization using four criteria.

Such tasks require dependable underwater wireless communications, which normally utilize the rapidly varying acoustic channel. Rigorous testing of underwater acoustic communication systems is necessary to develop a dependable network, however, the high offshore testing costs make this difficult. Though simulators could aid the development of such AUV communication systems, the few existing simulators focus upon simulating a single vehicle and, as such, do not provide tools for simulating underwater communication systems. In this paper we present an underwater communications simulation framework designed for the Unified System for Automation and Robotics Simulator (USARSim). This simulation tool is capable of modeling networked communications between, or with, AUVs by accurately characterizing the underwater acoustic channel. Details on this simulation framework are provided along with some results obtained during development of this tool.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"47 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115207657","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}
