Abstract:

The river water pumping station at SSAB in Borlänge is a critical part of the factory since it supplies the whole factory with cooling water. The problem with the river water pumping station is that the pressure in the pipes is very dependent on the large water consumers in the factory. The large consumers causes large variations in pressure and water level when they suddenly turns on and off. The second problem in the river water pumping station is that it can not pump enough water to the consumers during the warmer periods of the year. The aim of this thesis is to improve the control system

Abstract:

Control of anesthesia is one of the many tasks performed by anesthesiologists during surgery. It involves adjusting drug dosage by monitoring patient’s vital and clinical signs. A control system can replace this tedious and routine task, and allow the anesthesiologists to concentrate on more life threatening procedures. Because of large intra- and inter-variability in patients Pharmacokinetics and Pharmacodynamics responses, an adaptive controller is desirable. This thesis thoroughly investigates the L₁ Adaptive Control by applying it on 44 simulation cases which cover a wide range of patient

Second, control parameters for the quadrotors Proportional Integral Derivative (PID) controller are found by using empirically modiﬁed Tuning Rules (TRs) which are based on the I2PD model.

Abstract:

The benefits of good loop tuning in the process industries have long been recognized. Ensuring that controllers are kept well-configured despite changes in process dynamics can bring energy and material savings, improved product quality as well as reduced downtime. A number of loop tuning packages therefore exist that can, on demand, check the state of a loop and adjust the controller as necessary. These methods generally apply some form of upset to the process to identify the current plant dynamics, against which the controller can then be evaluated. A simple approach to the automatic tuning

A new method of adaptive impulse control is developed to precisely and quickly control the position of machine components subject to friction. Friction dominates the forces affecting fine positioning dynamics. Friction can depend on payload, velocity, step size, path, initial position, temperature, and other variables. Control problems such as steady-state error and limit cycles often arise when applying conventional control techniques to the position control problem.

Basicamente um Eletroestimulador Funcional (Functional Electrical Stimulation FES) se baseia na estimulação dos nervos motores via eletrodos cutâneos de modo a movimentar (contrair ou distender) os músculos, visando o fortalecimento muscular, a ativação de vias nervosas (reinervação), manutenção da amplitude de movimento, controle de espastici

Abstract:

An intelligent agent must be capable of using its past experience to develop an understanding of how its actions affect the world in which it is situated. Given some objective, the agent must be able to effectively use its understanding of the world to produce a plan that is robust to the uncertainty present in the world. This thesis presents a novel computational framework called the Adaptive Modelling and Planning System (AMPS) that aims to meet these requirements for intelligence. The challenge of the agent is to use its experience in the world to generate a model. In problems with large st

Abstract:

Le principe du système adaptatif réalisé consiste à prendre en compte les informations au fur et à mesure de leurs acquisitions et à les utiliser pour calculer directement les paramètres de commande sans passer par une identification du modèle mathématique proposé. On développe également une nouvelle méthode d'auto-réglage

Abstract:

Cette thèse s'intéresse à la question récurrente qu'est la résolution d'un problème pour un grand nombre de configurations différentes. Malgré l'augmentation constante de la puissance de calcul que l'on connait aujourd'hui, le traitement direct d'un tel problème reste souvent hors de portée. La technique qui est développée ici est basée sur l'utilisation de la Proper Generalized Decomposition (PGD) dans le cadre de la méthode LATIN. On étudie tout d'abord la capacité de cette technique de réduction de modèle à résoudre un problème paramétré pour un espace de conception donné. Lors du traitemen

Abstract:

Artificial Neural Networks have been widely probed by worldwide researchers to cope with the problems such as function approximation and data simulation. This thesis deals with Feed-forward Neural Networks (FNN's) with a new neuron activation function called Neuron-adaptive Activation Function (NAF), and Feed-forward Higher Order Neural Networks (HONN's) with this new neuron activation function. We have designed a new neural network model, the Neuron-Adaptive Neural Network (NANN), and mathematically proved that one NANN can approximate any piecewise continuous function to any desired accuracy

Abstract:

Motivation is important for learners. As the provision of education moves increasingly towards online delivery, keeping motivation high is a key challenge. The lack of personalized approaches traditionally delivered by human tutors increases drop out rates. This thesis investigates how a conversational agent, taking the role of a virtual tutor, could deliver personalised feedback on performance to learners. It also investigates the most effective emotional support to incorporate in this feedback in order to maintain learner motivation. How learners respond to feedback depends on many factors.
