   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

4. 2. Resource-Constrained Embedded Control and Computing Systems

   Author : Dan Henriksson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

   Abstract : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. READ MORE

5. 3. LQG-Based Real-Time Scheduling and Control Codesign

   Author : Yang Xu; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; Real-time system; Scheduling; Time-delay system;

   Abstract : Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. READ MORE

6. 4. Flexible Scheduling Methods and Tools for Real-Time Control Systems

   Author : Dan Henriksson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Simulation Tools; Delay Compensation; Feedback Scheduling; Real-Time Control;

   Abstract : This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. READ MORE
