   Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

4. 3. On Application Oriented Experiment Design for Closed-loop System Identification

   Författare :Afrooz Ebadat; Bo Wahlberg; Torsten Söderström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; closed-loop identification; experiment design for identification;

   Sammanfattning : System identification concerns how to construct mathematical models of dynamic systems based on experimental data. A very important application of system identification is in model-based control design. In such applications it is often possible to externally excite the system during the data collection experiment. LÄS MER

5. 4. Design of Optimal Control Processes for Closed-Loop Chain SCARA-Like Robots

   Författare :Mathias R Lidberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unpowered actuator.; SCARA-robot; closed-loop chain; manipulator;

   Sammanfattning : The design of optimal control processes for closed-loop chain SCARA-like robots is the subject of this thesis. In comparison with the well-known SCARA robot, the proposed new structure is characterized by the incorporation of an additional powered actuator, several unpoweredactuators and an additional link that gives a closed-loop chain robot.
