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

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

   Sammanfattning : Control and diagnosis of complex systems demand accurate information of the system state to enable efficient control and to detect system malfunction. 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
