1. 21. Force Feedback Control of a Semi-Active Shock Absorber

   University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan

   Author : Per Svennerbrandt; [2014]
   Keywords : Force feedback control; semi-active dampers; damper modeling; exact linearization;

   Abstract : Semi-active suspension systems promise to significantly reduce the necessary trade-off be-tween handling and passenger comfort present in conventional suspension systems by enabling active chassis and wheel control. Öhlins Racing AB have developed a semi-active suspension technology known as CES, Continuously controlled Electronic Suspension, based on solenoid control valves which are integrated into specially designed hydraulic dampers, and are currently developing control and estimation systems which will enable their application in advanced motorcycle suspensions.

3. 22. Fault Detection and Diagnosis for Brine to Water Heat Pump Systems

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Daniel Vecchio; [2014]
   Keywords : Fault detection and diagnosis; heat pumps; residuals; brine to water; model based.;

   Abstract : This research project is part of a wider project called Smart Fault Detection and Diagnosis for HeatPump Systems currently under development by the Royal Institute of Technology (KTH).Generally, maintenance, diagnosis and repair of heat pumps are manual operations. READ MORE

4. 23. Development and Evaluation of Model-Based Misfire Detection Algorithm

   University essay from Linköpings universitet/Fordonssystem

   Author : Linus Therén; [2014]
   Keywords : Model-Based; Misfire; Detection; Diagnosis; Kullback-Leibler; SVM;

   Abstract : This report present the work to develop a misfire detection algorithm for onboard diagnostics on a spark ignited combustion engine. The work is based on a previous developed model-based detection algorithm, created to meet more stringent future legislation and reduce the cost of calibration. READ MORE

5. 24. Fault diagnosis of a Fixed Wing UAV Using Hardware and Analytical Redundancy

   University essay from Fordonssystem; Tekniska högskolan

   Author : Michael Andersson; [2013]
   Keywords : Fault Diagnosis; Model based diagnosis; Redundancy; Autopilot; UAV; fixed-wing;

   Abstract : In unmanned aerial systems an autopilot controls the vehicle without human interference. Modern autopilots use an inertial navigation system, GPS, magnetometers and barometers to estimate the orientation, position, and velocity of the aircraft. In order to make correct decisions the autopilot must rely on correct information from the sensors. READ MORE

6. 25. A model-parameter invariant approach to HVAC fault detection and diagnosis

   University essay from KTH/Reglerteknik

   Author : Dario Papale; [2012]
   Keywords : ;

   Abstract : This thesis develops and experimentally evaluates a model-based detector for detecting actuator failures in HVAC systems which dynamically estimates the model parameters while performing detection. Specifically, this thesis considers actuator failures which result in the actuator valve sticks in an unknown (but constant) position. READ MORE
