5. 3. Observer Design and Model Augmentation for Bias Compensation with Engine Applications

   Author : Erik Höckerdal; Erik Frisk; Tomas McKelvey; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; observer; bias compensation; diesel engine; EKF; Automatic control; Reglerteknik;

   Abstract : Control and diagnosis of complex systems demand accurate knowledge of certain quantities to be able to control the system efficiently and also to detect small errors. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. READ MORE

6. 4. Safe, human-like, decision-making for autonomous driving

   Author : Dapeng Liu; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human-like behaviors.; imitation learning; Autonomous driving; reinforcement learning; decision making; safety;

   Abstract : Autonomous driving technology can significantly improve transportation by saving lives and social costs and increasing traffic efficiency and availability. Decision-making is a critical component of driving ability. Complex traffic environments and interactions between road users bring about many challenges in decision-making. READ MORE

7. 5. Model Error Compensation in ODE and DAE Estimators : with Automotive Engine Applications

   Author : Erik Höckerdal; Erik Frisk; James Peyton-Jones; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information technology; Informationsteknik; Automatic control; Reglerteknik;
