By using a basis-dependent Lyapunov function, a delay-dependent result on the H∞ performance of the filtering error system is presented. A sufficient condition for the existence of the filter is provided. It is shown that the filter can be obtained by solving a set of linear matrix inequalities (LMIs). A numerical example is given to demonstrate the efficiency of the proposed method.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116821191","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 fact that real-time navigation systems could have their performance compromised by the need of processing all this redundant information (all images acquired by a vision system, for example), this work proposes an automatic image discarding method using the Pearson's correlation coefficient (PCC). The proposed algorithm uses the PCC as the criteria to decide if the current image is similar to the reference image and could be ignored or if it contains new information and should be considered in the next step of the process (identification of the navigation area by an image segmentation method). If the PCC indicates that there is a high correlation, the image is discarded without being segmented. Otherwise, the image is segmented and is set as the new reference frame for the subsequent frames. This technique was tested in video sequences and showed that more than 90% of the images can be discarded without loss of information, leading to a significant reduction of computational time necessary to identify the navigation area.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121890224","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 technique offers considerable flexibility in designing controllers for all relevant variables. The main advantage of this technique is the possibility of selecting various control loops for a particular application problem. This is of paramount importance in control systems and power system engineering especially where all relevant variables may not be directly measured. As an example application, four different robust nonlinear excitation controllers are designed and compared to enhance voltage regulation of a power system. Simulation results carried out on a single machine infinite bus (SMIB) power system model show the enhancement of system stability and voltage regulation for different control structures regardless of the fault and changes in network parameters.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125941689","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}

Most of the existing identification methods of symmetrical IMs are, strictly speaking, valid only at stationary conditions, which limitation results in either poor dynamics excitation or gross approximation errors, depending on the working conditions of the motor. In this paper, the topic of identification of all electrical parameters of faulty IMs is addressed for the first time. A method for on-line observer-based estimation of all electrical parameters of IMs with faulty stator is presented aiming primarily at fault tolerant control and fault detection. The approach does not rely on any assumptions regarding the rotor angular speed and/or acceleration.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131353699","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 advent of BBW system offers a more accurate and continuous braking control, hence poses the possibility of introducing an advanced control algorithm for ABS system. The proposed algorithm aims to utilize this technology and the behavior of the model to optimize the wheel slip dynamics subject to system constraints. The final implementation of the controller embraces the decentralized control architecture of BBW system to independently control the brake torque at each four wheels. The performance of a wheel slip controller is validated through hardware-in-the-loop simulation (HiL), which consists of physical BBW brake calipers and the real-time nonlinear vehicle dynamic simulation model to accommodate the realistic brake-by-wire system.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128789201","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}

Optimality is defined via economical criteria related to steady-state operation requirements. Limits on the capacity of the power lines are taken into account via inequality constraints that are added to the optimization problem. Due to these inequality constraints, the resulting control law has a piecewise affine structure. Furthermore, the control action is distributed in the sense that a controller is assigned to each node and each controller communicates only with the controllers associated with the neighboring nodes. We prove that the resulting steady-state solution is optimal. The proposed control structure is a relaxation and an extension of classical \"automatic generation control\" in power systems, and can be interpreted as a fast acting real-time market for electrical power.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126224659","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}
