The goal is not to design new observers but to provide simple analytic conditions in order to check the weak local observability of the state. The analysis starts by providing a new definition of indistinguishable states in the case of unknown inputs. Then, in order to separate the effect of the known inputs from the effect of the unknown inputs on the system outputs, the state is augmented. This allows us to obtain the extension of basic properties, which hold in the case of known inputs. Starting from these properties, the paper provides a sufficient analytic condition for the state observability, which is called the extended observability rank condition. The proposed approach is used to derive the observability properties of two systems. The former is very simple while the latter is very complex and describes the fusion of visual and inertial measurements.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131320080","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}

With wheel slip constraints and certain faults, a passive fault-tolerant controller based on the low-high gain control is developed to maintain the system's stability and guarantee an acceptable performance. If the performance degrades under a given threshold, an active fault diagnosis (AFD) approach is used to isolate and to evaluate the fault more precisely. A reference adjustment technique (RAT) with the designed controller are used to guarantee the safe implementation of AFD. As soon as the diagnosis information is available, an accommodated controller is reconstructed to recover the degraded performance as best as possible. Finally, simulations of traction engine faults for a 4WD EV are conducted to illustrate the proposed scheme.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128855173","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}

It is known, even though the sliding mode technique is robust against unknown but bounded uncertainties, that the quality of fault reconstruction under real conditions is not as good as assumed in the design stage. This is often due to the fact that the unmodeled dynamics and external disturbances have a greater variability and dimension as expected. Even if the dimension is known, it is formally limited by the existence condition for an exponentially stable error dynamics. Therefore, H∞ criteria are derived to obtain a threshold for the accuracy of fault reconstruction during sliding motion. The validity and applicability of the design approach is demonstrated by the inverted pendulum benchmark.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534880","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 proposed scheduling policy takes into account feedback on nodes' health status and the quality of the information provided by the nodes to be scheduled. As a result, dynamically variable schedules are produced, adapted to the current status of the WSN.

In particular, the mathematical formulation in the context of singular PDE theory is utilized via system of first order quasi-linear singular PDEs within the nonlinear hyperbolic PDE setting to obtain single step state nonlinear transformation and feedback control law with prescribed closed loop dynamics. The solution of quasi linear singular PDE is guaranteed by the Lyapunov's auxiliary theorem and locally invertible analytic transformation is applied by the full state feedback law to yield desired stable hyperbolic PDE system with assignable dynamics. The simultaneous state transformation and feedback linearization are realized in one step, avoiding the restrictions existing in other approaches.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134487409","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}

New routines have been developed using standard libraries to improve portability and efficiency. A preliminary version was released previously by the authors, which achieved high performance. However, accuracy improvements have been necessary in order to make the new routines similar to the sequential ones in this aspect.
