The proposed method relies on innovation sequence generated by the conventional extended Kalman filter. The innovations would follow a Gaussian distribution under normal operation; however a fault, i.e., broken rotor bar, would change this underlying distribution. It has been shown that this change in the distribution is indicative of a fault. The proposed method uses readily available current measurements and no additional sensors are required. Further, the proposed method is robust to unbalanced supply voltage and load changes. Computer simulations are carried out for 4-hp squirrel-cage induction motor using MATLAB software. The results demonstrate the advantage of the proposed technique as it provides accurate estimates for broken rotor bar fault detection.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122230548","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 nonlinear characteristics of hydraulic turbine and the inelastic water hammer effects were considered to simulate the comprehensive behaviour of this dynamic process. The data-driven strategy has been suggested for deriving in a straightforward way a prediction filter able to reconstruct the fault affecting the hydroelectric system. The fault tolerant controller development requires the knowledge of the dynamic model of the monitored system, which is achieved by means of a model predictive control scheme that compensates the fault. These features of the work represent an important point when plug-and-play implementations are considered for a viable application of an effective fault tolerant methodology. In particular, by means of this methodology, the fault tolerance properties are achieved by using an active approach. It is assumed that the fault considered in this work affects the electric servomotor used as a governor. The performances obtained are compared to those of a passive solution already implemented by the authors for the same hydroelectric system.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125162777","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 trajectories are optimally selected using quantization of the post jump locations of the PDMP. The performance of this approach is evaluated both theoretically and on a numerical example of a magnetic suspension system subject to failures.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117071000","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}

False data injections on control and/or measurement signals of a Fault-Tolerant Control System (FTCS) can be treated as detectable virtual actuator or sensor faults. In this case, the FTCS can automatically accommodate false data injections by triggering the controller reconfiguration mechanism at detection time given by the mode-based Fault Detection and Isolation (FDI) algorithm. We show that an intelligent adversary can destabilize the non minimum phase plant of the FTCS by designing a false data injection attack on the control signal while remaining undetectable from any passive FDI algorithm. By using a confining coding method able to block the attack signal on a minimum number of encoded control signals, this paper proposes to transform stealthy false data injections into detectable attacks from an active FTCS based on a switching Linear Quadratic Gaussian (LQG) controller.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121398475","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}

Following the concept of reference model control, the main idea is to keep untouched the nominal control parameters, where in addition the nominal controller remains a part of the reconfigured control loop. The full state control tenet is applied for nominal control strategy and the static output control principle for the compensation control law specification in the so called cascade reconfiguration structure. Analyzing as a mixed control problem, new conditions for control structure parameter design are introduced and proven. The obtained results, offering the sufficient and necessary design conditions, are illustrated with a numerical example to note the effectiveness of the proposed approach.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"12 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131456603","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}
