2. 1. Architectures and Performance Analysis of Wireless Control Systems

   Author : Burak Demirel; Mikael Professor; Tamer Basar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; wireless networks; optimal control; time-delays; packet losses; linear-quadratic control; supervisory control; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Modern industrial control systems use a multitude of spatially distributed sensors and actuators to continuously monitor and control physical processes. Information exchange among control system components is traditionally done through physical wires. READ MORE

4. 2. On performance limitations of large-scale networks with distributed feedback control

   Author : Emma Tegling; Henrik Sandberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. READ MORE

5. 3. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

   Author : Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

   Abstract : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. READ MORE

6. 4. On input design in system identification for control

   Author : Märta Barenthin; Bo Wahlberg; Håkan Hjalmarsson; Torkel Glad; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Systemidentifiering; Automatic control; Reglerteknik;

   Abstract : There are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation. READ MORE

7. 5. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

   Author : Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

   Abstract : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. READ MORE
