Furthermore, the UD decomposition is adopted to suppress the filter divergence. The experiment result shows that the design satisfies the precision requirements for unmanned aerial vehicles or other tactical applications.","PeriodicalId":6304,"journal":{"name":"2013 9th Asian Control Conference (ASCC)","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77071105","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}

This grid connected wind energy conversion system (WECS) is composed of DFIG and two back-to-back PWM voltage-source converters in the rotor circuit. A mathematical model of the machine, derived in an appropriate dq reference frame is established. The grid voltage oriented vector control is used for the grid side converter (GSC) in order to maintain a constant DC bus voltage and to compensate for reactive power at the power network. The stator voltage orientated vector control is adopted in the rotor side converter (RSC) control strategy, providing efficient handling of active and reactive power at the stator, as well as a maximum power point tracking (MPPT) method for the DFIG-based wind turbine. The proposed system is simulated for different operating conditions to illustrate the reliability of the control technique. Corresponding system simulation results under nonlinear load variations and wind speed transients are presented to demonstrate the significance of MPPT in WECS, and the effectiveness of adopted control technique.","PeriodicalId":6304,"journal":{"name":"2013 9th Asian Control Conference (ASCC)","volume":"46 6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76173162","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}

This new approach considers minimum number of information flow links and local measurements only, yet a uniform distribution of unicycles rotated around the target is accomplished. The asymptotic collective behavior is analyzed based on the block diagonalization of circulant matrices by a Fourier transform.

The detection precision may change heavily with traffic congestion extent, illumination variance and vehicle moving speed. To overcome the problem of weak traffic scene adaptability, a robust vehicle detection method is proposed using the inter-relationship of consecutive multiframes. The changing of frame content is a process including abrupt and gradual variation caused by the objects' color and intensity changing. Thus, the local maxima of consecutive frames' objective function are constructed to determine the best vehicle detection frame. This function is invariant to traffic congestion and vehicle speed, and avoids vehicle segmentation from frames. For illumination invariance, traditional threshold method is substituted by peak searching method. Experiments show that the proposed method implements stably in different traffic scenes than traditional methods, and with the real-time performance and higher detection precision.","PeriodicalId":6304,"journal":{"name":"2013 9th Asian Control Conference (ASCC)","volume":"25 5 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83159848","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 dynamics of the Hover are described by a 6th order model taking as state variables the angles of roll, pitch, yaw and associated rates. The design problem has been formulated via parametric H∞ loop shaping control by describing the uncertainly as perturbations to normalized coprime factors of the shaped plant. The design strategy is characterized by the insertion of a free parameter that aims to increase the flexibility of the design ensuring robust stabilization of the linear parameter-varying system. For the existence of a gain-scheduled parametric H∞ loop shaping controller, a set of sufficient conditions has been derived in an LMI framework.

Recently a new CLOE method called as DIDIM for Direct and Inverse Identification Model needing only actual forces/torques data was validated on rigid robots. This method avoids the drawbacks of the usual CLOE method. With the DIDIM method, the optimal parameters minimize the 2-norm of the error between the actual forces/torques and the simulated ones. It is based on a closed-loop simulation of the robot using the direct dynamic model, the same structure of control-law and the same reference trajectory for both the actual robot and the simulated one. The DIDIM method simplifies dramatically the non-linear Least Squares problem by using the Inverse Dynamic Model in order to obtain an analytical expression of the simulated forces/torques which are linear in the parameters. This explains why the DIDIM method has a fast convergence. In this paper, the DIDIM method is compared with the usual CLOE method which uses the actual positions as output.
