2. 1. Active Vibration Control of Multibody Systems : Application to Automotive Design

   Author : Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

   Abstract : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. 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. 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

6. 4. Industry applications of multivariable control

   Author : Wolfgang Birk; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : In the face of environmental regulations, optimization of industrial processes becomes necessary. This doctoral thesis summarizes the results of three application-driven projects in automatic control that were aimed at process optimization in the steel industry. READ MORE

7. 5. Linear control of systems with actuator constraints

   Author : Stefan Rönnbäck; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : This thesis deals with the problem of how to design a linear and time invariant controller (continuous- or discrete-time) for a SISO- or SIMO-system with amplitude constraints in the actuator. One of the basic ideas is to model the constraints by means of a 'disturbance' δ acting at the input of the process. READ MORE
