  4. 7. On low order controller synthesis using rational constraints

    Author : Daniel Ankelhed; Anders Hansson; Anders Helmersson; Anders Forsgren; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity synthesis; Linear Matrix Inequalities; rank constraints; polynomial constraints; interior point methods; Automatic control; Reglerteknik;

    Abstract : In order to design robust controllers, H-infinity synthesis is a common tool to use. The controllers that result from these algorithms are typically of very high order, which complicates implementation. READ MORE

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE

  6. 9. On H2 and H-infinity Optimal Control of Mass-Spring Networks with Power System Applications

    Author : Johan Lindberg; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electric power systems are undergoing huge changes due to the shift from conventional power production to more renewable-based generation like solar and wind. This is primarily driven by the need to mitigate climate change by reducing CO2 emissions. READ MORE

  7. 10. Steering control for haptic feedback and active safety functions

    Author : Tushar Chugh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; position control; coupled stability; passivity; steering system; uncoupled stability; transparency; active safety; haptic feedback; torque control; state estimation;

    Abstract : Steering feedback is an important element that defines driver–vehicle interaction. It strongly affects driving performance and is primarily dependent on the steering actuator's control strategy. READ MORE
