Because the complexity of traditional ducted fan UAV's control organ, which has strong air coupling, so there has big challenge if this kind of ducted fan UAV is used in the complex urban environment. A differential control type for ducted fan UAV has presented in this paper, through dynamics analysis and CFD simulation to the traditional ducted fan UAV and differential control type, the differential control type can keep the yaw stability of aircraft when the control flaps has a rational angle and stable lift when the control flaps become, meanwhile it can control the pitch and roll attitude through the differential motion of control flaps. So this differential control type is feasible and possesses some advantage over relative to traditional type if processing reasonable optimization and design.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121623300","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}

Three most widely used turbulence models, Standard Spalart-Almaras, Realizable k-ε and SST k-ω, were tested and compared. The resource consumption study was based on the benchmark of 3000 iterations.

The regulation of the nonlinear system over a wide range of operation is handled by a number of linear local MPCs, each is designed based on a local State Space model which describes the dynamic characteristics of the system in a certain level of operation. At each certain time of operation, only one local MPC is active while others are in standby mode and switching among the local MPCs is taken place when the system changes its working condition. In order to produce a “bumpless transfer” during the switching, a Feedback of External Manipulated Variable (FEMV) is provided to the all local MPC controllers. The proposed method is applied to real time Gaseous Pilot Plant and results from the test show that the proposed MMPC improves the performance of nonlinear control system.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121504401","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}

A new optimization model which considers the dynamic characteristics of different gears of vehicle gear transmission is presented. As an example, the dynamic characteristic optimization model of certain vehicle gear transmission is established through the Isight software integrate the nonlinear dynamic programs of different gears and then solved with NSGA-II method. The optimization results show that the maximum gear mesh forces of commonly used gears are effectively reduced, while the maximum gear mesh forces of less used gears almost remain unchanged, which prove the feasibility of the optimization model and provide reference for the dynamic characteristic improvement of vehicle gear transmission.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131314625","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 developed technique used measured positions and orientations (poses) of the linear axis to identify the existing deviations from an ideal linear axis model in six degrees of freedom (DOF). Based on the measured data B-Splines were used to model the external axis in all six DOF along its entire travel distance. The resulting model allowed the prediction of the linear axis pose with the help of the calculated splines. With this predictable pose the absolute accuracy of any standard industrial robot can be enhanced that is located on the linear axis. For adaptive processes this routine forms the basis of positioning a standard industrial robot regarding its absolute accuracy in combination with the advantageous workspace capability of an external axis. The described method was evaluated and tested on a standard industrial robot system using a standard external linear axis. With this modelling the absolute accuracy of the linear axis was improved close to its repeatability error. All measurements to determine the position and orientation of the linear axis were done with a laser tracker.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131682219","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 simulation results illustrate that both the load torque and torque response time of the generator are the critical factors affecting the stability properties of the mode switch.

Unfortunately, this game requires a minimum of two players making it impossible for users who wish to train or play by themselves. To solve this issue, a robotic air hockey table capable of emulating a human player has to be created. In this paper, we have developed a computer vision system to detect and track the movements of the puck which is used to predict the final position of the puck in real time. Once the system predicts the final location of the puck, an electrical linear actuator capable of high speed and acceleration is activated which drives the mallet to block the goal. This paper will also discuss various problems encountered and possible future solutions to eradicate them.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130261814","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}
