This could be achieved by means of the inclusion of Fault Tolerant Control (FTC) mechanisms. In this paper, a FTC based on fault hiding approach is proposed for a non-holonomic mobile robot. First, a Sliding Mode Controller (SMC) is designed to control the robost and to cope with modelling uncertainty. Later on, it is enhanced to take into account actuator faults leading to a fault hiding approach for the sliding mode fault-tolerant control of the robot. Results using simulated fault scenarios are presented to illustrate the performance of the proposed approach.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132997002","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 enhancements rely on combining modern fault detection and diagnosis (FDD) techniques with a robust envelope protection algorithm. The FDD system is able to detect and isolate partial or total losses of angle of attack sensors. The angle of attack is not a directly controlled variable in the flight control system, but is used to protect the aircraft from exceeding the flight envelope. To avoid the state-of-practice degradation towards an unprotected control law in case of a total angle of attack sensor loss, longitudinal protection law functionalities independent of the lost measurements are proposed. They provide satisfactory prevention of reaching difficult flight conditions and can be operated together with the nominal command and stability augmentation system. This paper discusses the protection law design in conjunction with the sensor monitoring scheme and the nominal inner loop control law. The latest results of an extensive industrial validation and verification campaign are reported.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126174255","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 method integrates the fault estimation and fault-tolerant control units in a dynamic system, which is less complex and more reliable than the separately designed self-healing architectures. In this paper, the model reference approach is used to obtain a tracking error dynamic equation. Following this, an augmented error system is constructed by taking the fault as an auxiliary vector. Based on the augmented error system, a fault estimator/controller is designed to achieve robust fault-tolerant control and robust fault estimation simultaneously. The design conditions for the proposed fault estimator/controller are transformed as a set of linear matrix inequalities, which can be easily solved. Finally, numerical simulation results are given to demonstrate the effectiveness of proposed method.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057905","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}

Initially, the TE is calculated for the pathways which are considered as direct based on the process topology. Thereafter, the Direct Transfer Entropy (DTE) is employed to discriminate spurious and/or indirect pathways.

For instance, an oil leakage in a damper could cause a reduction of the damping force. The fault estimation requires a modeling of the damper fault (both multiplicative and additive fault models can be used). Three observer-based approaches are compared for fault estimation: an observer using fast adaptive fault estimation (FAFE) approach (used for estimation of additive faults), a parametric adaptive observer (AO) and a switched LPV observer (LPVO) (both intended to estimate mulplicative faults). Since the damper fault estimation is strongly affected by the unknown road disturbances, an H∞ performance objective is used to reduce the effect of disturbances on the estimation error for performance assessment. Some simulations are performed on a quarter car model to validate these methodologies and a comparison is then given to show the interest of each method.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132661804","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 agents are partitioned into independent nodes, providing the control inputs and monitoring the system, and dependent nodes, controlled by local interaction laws and subject to faults. The approach uses a decentralized state estimation algorithm allowing the independent nodes to estimate both the state of the dependent nodes and the control input components computed by the other independent nodes, in a completely decentralized way, without requiring communication among the independent nodes. Suitable detection and isolation residuals and thresholds are derived. Detectability and isolability sufficient conditions are provided.

The flow dynamics in each branch is described by the continuity equation of Saint-Venant model and Green-Ampt infiltration formula, while the initial states are assumed to be unknown. A methodology is then proposed to optimize the placement of sensors, with the purpose of estimating those states by a least square error minimization between measured and estimated water heights. Considering the method of variational calculus to solve for this minimization, a criterion based on the computed adjoint state is used to maximize the output sensitivity by appropriate sensor locations. A case-study of three small surface runoffs connected together at a point where two upper flows stream down into the third one is considered as an application example, and numerical simulations are provided with different measurement scenarios to validate the proposed optimal sensor location technique as well as the estimation method.","PeriodicalId":223249,"journal":{"name":"2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126906718","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}

In the off-line phase, this fault diagnosis approach starts from obtaining the minimal structurally over-determined (MSO) sets using the system model and the set of available sensors. These MSO sets are converted into a graph. This graph is further divided into various subgraphs using a partition algorithm. Each subgraph corresponds to a subsystem. From various subgraphs, different local fault signature matrices for various subsystems are obtained. Finally, in the on-line phase, using various local fault signature matrices, a set of diagnoser agents are created that allow the global diagnosis in a large scale system. The entire proposed distributed fault diagnosis approach is divided into five different blocks. In order to illustrate the application of the proposed approach, a case study based on the Barcelona drinking water network (DWN) is used.","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":"115678376","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}
