1. 31. On Analysis and Implementation of Iterative Learning Control

   Författare :Mikael Norrlöf; Svante Gunnarsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ILC; Industrial robot control;

   Sammanfattning : Many of the control systems used in factory production today are programmed to perform the same task repeatedly. In particular this is the case for industrial robots where the same motion is performed every time the same program is executed. LÄS MER

3. 32. Model-Based Control of Gasoline Partially Premixed Combustion

   Författare :Gabriel Ingesson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-Sensor Feedback; Model Predictive Control; Model-Based Controller Design; Partially Premixed Combustion;

   Sammanfattning : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.

4. 33. On the control of systems with input saturation or periodic disturbances

   Författare :Kirthi Sarachchandra Walgama; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This thesis deals with two important problems in control theory and practice. The first problem is the windup problem in controllers where there exist non-linearities between the controller output and the process input. LÄS MER

5. 34. Robotic Assembly and Contact Force Control

   Författare :Andreas Stolt; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Modern industrial robots are traditionally programmed to follow desired trajectories, with the only feedback coming from the internal position/angle sensors in the joints. The robots are in general very accurate in tracking the desired motion, and they have become indispensable in many applications, such as spot welding and painting in the automotive industry. LÄS MER

7. 35. Losing control and developing concerns : The complexities of ageing postural control and fall-related concerns

   Författare :Mascha Pauelsen; Lars Nyberg; Ulrik Röijezon; Irene Vikman; Jorunn Lægdheim Helbostad; Luleå tekniska universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ageing; postural balance; postural control; sensory and motor systems; fall-related concerns; fear of falling; neurological models; Physiotherapy; Fysioterapi;

   Sammanfattning : With the world population shifting its proportions towards higher ages, it is imperative to increase healthspan rather than lifespan, both for the sakes of community sustainability as well as individual quality of life. One of the main means to obtain healthy ageing, is a concept called active ageing, as activity has shown to slow down the natural ageing process. LÄS MER
