2. 1. Integrated Control and Real-Time Scheduling

   Author : Anton Cervin; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

   Abstract : The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. READ MORE

4. 2. 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

5. 3. Towards the Integration of Control and Real-Time Scheduling Design

   Author : Anton Cervin; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Control; Scheduling; Co-Design; Deadlines; Performance; Simulation; Feedback;

   Abstract : The thesis deals with scheduler and controller co-design for real-time control systems. The overall goal is higher resource utilization and better control performance. One goal is to minimize the performance loss due to jitter and control delays. READ MORE

6. 4. Response time analysis for implementation of distributed control systems

   Author : Ola Redell; KTH; []
   Keywords : real-time systems; response time analysis; control systems; control jitter;

   Abstract : Methods for performing response time analysis of real-timesystems are important, not only for their use in traditionalschedulability testing, but also for deriving bounds on outputtiming variations in control applications. Automatic controlsystems are inherently sensitive to variations in periodicityand end-to-end delays. READ MORE

7. 5. Quality of control and real-time scheduling : allowing for time-variations in computer control systems

   Author : Martin Sanfridson; KTH; []
   Keywords : real-time scheduling; sampled-data control. Performance measure; quality of control;

   Abstract : The majority of computers around us are embedded in productsand dedicated to perform certain tasks. A specific task is thecontrol of a dynamic system. The computers are ofteninterconnected by communication networks forming a distributedsystem. READ MORE
