Most grid based collision avoidance approaches use Lee's algorithm to find an optimal collision-free path. The drawback of this algorithm is the long runtime for large grids. To reduce this runtime, in this work the A* search is used instead of Lee's algorithm. The algorithm additionally regards the physical constrains of the vessel and pays attention to the COLREGs. The runtime and the resulting path of Lee's algorithm and the A* search are compared in computational experiments. Furthermore, the performance of the collision avoidance on a real vessel on the Lake Constance is presented.","PeriodicalId":305110,"journal":{"name":"2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114892044","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}

Robot dynamics have generally uncertainties, including parameters variations, unknown nonlinearities of the robot, payload variations, and torque disturbances form the environment. The cost function of the NMPC is defined in such a way that by adjusting its weighting parameters, the end-effector of the robot tracks a predefined geometry path in Cartesian space with a constant velocity. Moreover, in order to cope with uncertainties in the robot model neural networks with Levenberg-Marquardt training algorithm will be used to estimate adaptively the model of the robot. The closed-loop stability is demonstrated using Lyapunov theory. Simulation results of the proposed control method applied to a 3-DOF manipulator actuated by DC servomotors show satisfactory results for trajectory tracking in work space of the robot.","PeriodicalId":305110,"journal":{"name":"2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122371759","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}

Optimization algorithm for finding the parameters for the function of the pole radius is presented. The proposed filters are tested using sinusoid, rectangle, and ECG signals. Computer simulations demonstrate that the proposed time-varying FIR filters outperform traditional time-invariant FIR filters.","PeriodicalId":305110,"journal":{"name":"2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121541559","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 process output is termed the pass profile and when each pass is completed, resetting to the starting location occurs before the next pass begins. On each pass the previous pass profile acts as a forcing function on, and hence contributes to, the dynamics produced. The result can be oscillations that increase in amplitude form pass-to-pass and which cannot be controlled by standard control action. There has been a considerable volume of profitable work on the development of a control theory for these processes with more recent focus on the design of control laws. The novel contribution of this paper is a new design algorithm which makes more use of available previous pass profile information and reduces the conservativeness present in existing alternatives.","PeriodicalId":305110,"journal":{"name":"2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122256660","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 a normal working mode, the vehicle is manually controlled from Mobile Command Center (MCC) located on the seashore or on a ship. However, when a radio-connection between the vehicle and the MCC is disrupted, the USV has to independently reach a destination point, along a path fixed by a Route Fixing System (RFS). In the paper, a solution is presented in which the role of RFS is played by a Canonical Genetic Algorithm (CGA). Effectiveness of this algorithm was tested experimentally on artificial images imitating a sea chart. Results of the experiments are presented at the end of the paper.","PeriodicalId":305110,"journal":{"name":"2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131379606","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}
