Full textDistributed systems have two main characteristics: they are complex and subject to failures. So, the verification and the study of fault tolerance in such systems are two major issues. In this thesis, we propose a model-checking verification technique for distributed systems. We present and prove an algorithm, based on partial orders, which builds a small subset of the whole set of states of a distributed system. In the reduced generated graph, it is still possible to verify stable properties of the considered system. We then study self-stabilizing systems which are fault tolerant distributed systems. Self-stabilizing systems are systems which, from any initialization, eventually behaves correctly, regarding to their specifications. The drawback of such systems is that they cannot determine whether or not they verify their specifications. In this thesis we propose a new model, in which the system can decide if it verifies its specification by introducing a new abstraction called observer. With this model, we prove that if there exists a synchronous self-stabilizing distributed solution for some problem in a distinguished network, then there exists a synchronous self-stabilizing distributed solution for the same problem in the same network which accept an observer. Finally, we introduce the notion of a probabilistic observer and we prove that such an observer allows to decide for a larger class of self-stabilizing systems than deterministic observers

Full textThe technique of proportional navigation is applied to a three dimensional missile-target engagement model. A Luenberger observer is developed to reduce the effects of noise or jamming to the missile's seeker head. A ground observer which computes the deviations in target position and velocity and uplinks the deviations to the missile is also evaluated using the Kalman Filter theory to determine the benefits of the additional information provided to the missile

Full textCoccoliths, in cells or detached, from coccolithophores are calcite plates with highly backscattering signal.Coccolithophore blooms are visible from space and are currently quantified by Calcite algorithm fromNASA applied to Ocean Color data. Coccoliths impact also the Suspended Particulate Matters (SPM) product from Ifremer, well established in the Northwest european continental shelf. Although these algorithms are independent, they are based on the same basic concepts, but Ifremer algorithm is more adaptable and allows to link up with other particles than coccoliths, as the resuspended matters or aggregates.Coccolithophore blooms identification over 18 years, from bay of Biscay to South Irelands has been established by a spectral method, allowing to discriminate coccoliths from SPM. Blooms follow the continental slope northward in connection with the seasonal variability of irradiance. The interannual variability observed indicates a slight decrease of blooms, with a very poor productive year in 2014.Data from PELGAS cruises in May in the Bay of Biscay highlight the strong correlation between SPM product and the in situ turbidity in coccolithophore blooms.This parameter can be considered a a good proxy for the blooms monitoring and for the description of their vertical structure. Hydrological in situ data show a stronger occurrence in less stratified environment, with lower temperatures and higher salinity.The sensitivity of the satellite to the presence of coccoliths has benn evaluated based on in situ observations from cruises in the Bay of Biscay and in Patagonia. This sensitivity is variable due to a lot of inherent factors, to the coccoliths/coccospheres proportion and to the taxonomic composition which has been rich in May 2016 in the Bay of Biscay

Blåberg, Christian. "Chest Observer for Crash Safety Enhancement." Thesis, Linköping University, Department of Electrical Engineering, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-12229.
Full textFeedback control of Chest Acceleration or Chest Deflection is believed to be a good way of minimizing the risk of injury. In order to implement such a controller in a car, an observer estimating these responses is needed. The objective of the study was to develop a model of the dummy’s chest capable of estimating the Chest Acceleration and the Chest Deflection during frontal crashes in real time. The used sensor data come from car accelerometer and spindle rotation sensor of the belt, the data has been collected from dummies during crash tests. This study has accomplished the aims using a simple linear model of the chest using masses, springs and dampers. The parameters of the model have been estimated through system identification. Two types of black-box models have also been studied, one ARX model and one state-space model. The models have been tested and validated against data coming from different crash setups. The results show that all of the studied models can be used to estimate the dummy responses, the physical grey-box model and the black-box state-space model in particular.
Genom att använda återkoppling av storheterna bröstacceleration och bröstintryck antas man kunna minska risken för skador vid krockar i personbilar. För att kunna implementera detta behövs en observatör för dessa storheter. Målet med denna studie är att ta fram en modell för att kunna skatta accelerationen i bröstkorgen samt bröstintrycket i realtid i frontala krockar. Sensordata som använts kom från en accelerometer och en givare för att mäta rotationen i bältessnurran. Detta har gjorts genom att modellera bröstkorgen med linjära fjädrar och dämpare. Dess parametrar har skattats från data från krocktester från krockdockor. Två s.k. black-box-modeller har också tagits fram, en ARX-modell och en på tillståndsform. Modellerna har testats och validerats mha data från olika sorters krocktester. Resultaten visar att alla studerade modeller kan användas för att skatta de ovan nämnda storheterna, den fysikaliska modellen och black-box-modellen på tillståndsform fungerade bäst.
Rytterstedt, Peter. "Observer for a vehicle longitudinal controller." Thesis, Linköping University, Department of Electrical Engineering, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-8820.
Full textThe longitudinal controller at DaimlerChrysler AG consists of two cascade controllers. The outer control loop contains the driver assistance functions such as speed limiter, cruise control, etc. The inner control loop consists of a PID-controller and an observer. The task of the observer is to estimate the part of the vehicle's acceleration caused by large disturbances, for example by a changed vehicle mass or the slope of the road.
As observer the Kalman filter is selected. It is the optimal filter when the process model is linear and the process noise and measurement noise can be modeled as Gaussian noise. In this Master's thesis the theory for the Kalman filter is presented and it is shown how to choose the filter parameters. Simulated annealing is a global optimization technique which can be used when autotuning, i.e., automatically find the optimal parameter settings. To be able to perform autotuning for the longitudinal controller one has to model the environment and driving situations.
In this Master's thesis it is verified that the parameter choice is a compromise between a fast but jerky, or a slow but smooth estimate. As the output from the Kalman filter is directly added to the control value for the engine and brakes, it is important that the output is smooth. It is shown that the Kalman filter implemented in the test vehicles today can be exchanged with a first-order lag function, without loss in performance. This makes the filter tuning easier, as there is only one parameter to choose.
Change detection is a method that can be used to detect large changes in the signal, and react accordingly - for example by making the filter faster. A filter using change detection is implemented and simulations show that it is possible to improve the estimate using this method. It is suggested to implement the change detection algorithm in a test vehicle and evaluate it further.
