2. 1. On System Identification and Acoustic Echo Cancellation

   Author : Per Åhgren; Peter Stoica; Peter Händel; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic echo cancellation; stereophonic acoustic echo cancellation; doubletalk detection; adaptive beamforming; adaptive filtering; system identification; recursive system identification; loudspeaker impulse response estimation; Signal processing; Signalbehandling;

   Abstract : The topic of acoustic echo cancellation has received a lot of interest over the years. Even though the topic is relatively old, the increasing demand for hands-free telephony has made it more important than ever before. READ MORE

4. 2. Learning in the Loop : On Neural Network-based Model Predictive Control and Cooperative System Identification

   Author : Rebecka Winqvist; Bo Wahlberg; Cristian R. Rojas; Axel Ringh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning; Model Predictive Control; System Identification; Optimal Transport; Inlärning; Modellprediktiv reglering; Systemidentifiering; Optimal transport; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Inom reglerteknik har integrationen av maskininlärningsmetoder framträtt som en central strategi för att förbättra prestanda och adaptivitet hos styrsystem. Betydande framsteg har gjorts inom flera viktiga aspekter av reglerkretsen, såsom inlärningsbaserade metoder för systemidentifiering och parameterskattning, filtrering och brusreducering samt reglersyntes.

5. 3. Assessment of cerebrospinal fluid system dynamics : novel infusion protocol, mathematical modelling and parameter estimation for hydrocephalus investigations

   Author : Kennet Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknik; hydrocefalus; infusionstest; utflödeskonduktans; systemidentifiering; Medical technology; Medicinsk teknik;

   Abstract : Patients with idiopathic normal pressure hydrocephalus (INPH) have a disturbance in the cerebrospinal fluid (CSF) system. The treatment is neurosurgical – a shunt is placed in the CSF system. The infusion test is used to assess CSF system dynamics and to aid in the selection of patients that will benefit from shunt surgery. READ MORE

6. 4. On input design in system identification for control

   Author : Märta Barenthin; Bo Wahlberg; Håkan Hjalmarsson; Torkel Glad; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Systemidentifiering; Automatic control; Reglerteknik;

   Abstract : There are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation. READ MORE

7. 5. Hydrobatics: Real-time Control, Simulation and Learning for Underactuated AUVs in Agile Maneuvers

   Author : Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Massimo Caccia; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utonomous Underwater Vehicles; Underactuated Systems; Model Predictive Control; Hybrid Systems; Simulation; System Identification; Adaptive Sampling; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Modelprediktiv kontroll MPC ; Systemidentifiering; Adaptiv mätning; Fältförsök; Cyber-fysikaliska System CPS .; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are either designed as flight style, optimized for range and speed, or hover style, optimized for precise maneuverability.
