The router dynamics changes instantaneously when the fault occurs causing the undesirable instability in the queue length. To improve the dynamics of TCP/AQM networks, suitable controllers (stable and optimal) are synthesized using the concept of canonical controller in real time. This makes the network to maintain its stability. The main feature of this fault accommodation technique is that it solely relies on the input-output trajectories generated by the actual plant model (without having its exact knowledge) and on the performance specifications given by the desired behavior. The least restrictive controller satisfying the desired behavior is chosen based upon the generated trajectories.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124773223","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}

Feedback linearization is designed to control the attitude stability in inner loop, traditional PID is designed to follow trajectory in accordance with pre-planned paths based on the Qball-X4 nonlinear model. For taking care of faults occurred in the UAV during the flight, reconfigurable control allocation is implemented together with the above controllers. Performance of constrained optimization algorithm for reconfigurable control allocation design — Fixed-point (Fix) algorithm with applications to Qball-X4 is evaluated under different partial-loss fault cases. Various simulation results have been provided to demonstrate the validity of the fault tolerant control system design and the effectiveness of the reconfigurable control allocation design in trajectory tracking control.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126919802","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 key point to ensure fault tolerance is the separation between healthy and faulty closed-loop behavior. Here we achieve this through set theoretic operations upon sets describing the healthy/faulty behavior of the system. The results rely both on an appropriate choice for the exogenous signals and on fixed point conditions for a nonlinear mapping which describes the gap between the nonlinear system and a linearized model in the functioning interval. A reference governor is employed such that, under a receding horizon technique, only feasible exogenous signals are provided to the system.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"76 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130604793","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 tests make it possible to isolate faults, which are generally not isolable, but can be distinguished if the system is brought into specific operating points. The basis for the test signal selection is a graph that represents the couplings among the external and internal signals of the system and the faults. This graph is used to identify edges that disappear under certain operating conditions and prevent a fault from changing the system behavior in this operating point. The test generation method is illustrated by a process engineering example.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126272344","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}

For reducing the network load and thus minimizing the uncertainty caused by transmission delay or packet dropout, instead of transmitting all measurements of velocity sensors at each sampling time, only one velocity sensor can have access to the network to transmit its measurement. In order to increase accuracy and rapidity of fault detection in motor of Drone, an approach based on Multi Sequential Probability Ratio Test for residual classification and fault detection of each motor is proposed. Then in function of accepted hypothesis of each sequential test a new communication sequence is chosen from ensemble of admissible communication sequences which preserves more medium access to a sub-system (motor) with more deviation from its normal condition.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125787844","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}

For this purpose, a state estimation scheme has been developed using an adaptive unscented Kalman filter (AUKF) approach. A fuzzy-based decision making (FDM) algorithm is introduced to diagnose sensor and/or actuator faults. The proposed fault detection and identification (FDI) approach is utilized to recursively correct the measurement vector and the model used for state estimation and prediction in the MPC formulation. The performance capabilities of the proposed FTC methodology is demonstrated by conducting series of simulation studies on a benchmark continuous stirred tank reactor (CSTR). Analysis of the simulation results reveals that the FTC scheme facilitates significant recovery in the closed loop performance particularly on occurrence of multiple sequential faults.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132331651","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 main idea of this FTC method is to reconfigure the control loop such such that the nominal controller could be still used without need of retuning it. That is, the plant with the sensor fault is modified adding the virtual sensor block that masks this fault and allows the controller to see the same plant as before the fault. This virtual sensor is designed using polytopic LPV techniques and Linear Matrix Inequalities (LMIs). The LPV state feedback controller is designed for quadratic H2/H∞ performance using a polytopic representation of the system that leads to solve a finite number of algebraic LMIs. To assess the performance of the proposed approach a two degree of freedom helicopter is used.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115474955","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 reactive layer of the FD agents is based on neural networks models for residuals generation with adaptive threshold.

To achieve the required level of data quality in online water quality monitoring, a system for fault tolerant control was developed. A modular approach was used, in which a sensor and station management module is combined with a data validation and an event detection module. The station management module assures that all relevant data, including operational data, is available and the state of the monitoring devices is fully documented. The data validation module assures that unreliable data is detected, marked as such, and that the need for sensor maintenance is timely indicated. Finally, the event detection module marks unusual system states and triggers measures and notifications. All these modules were combined into a new software package to be used on water quality monitoring stations.","PeriodicalId":253370,"journal":{"name":"2010 Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114654193","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}
