4. 2. Stochastic Event-Based Control and Estimation

   Author : Toivo Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

   Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

5. 3. 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

6. 4. Fixed structure LQ design with applications

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

   Abstract : This thesis deals mainly with the problem of designing structure constrained controllers (or fixed structure control design) which is a problem that occurs in many industrial control applications. In process industry for example, almost all control loops are closed with commercial PI controllers (which have specified structures). READ MORE

7. 5. Anti-windup and Control of Systems with Multiple Input Saturations : Tools, Solutions and Case Studies

   Author : Jonas Öhr; Mikael Sternad; Anders Ahlén; Tore Hägglund; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Anti-windup compensator; saturating actuator; amplitude limiter; rate limiter; path anti-windup; double integrator; time-optimal control; container crane; spreader; hydraulic cylinder; Reglerteknik; Automatic control; Reglerteknik;

   Abstract : Control of linear systems with saturating actuators are considered and anti-windup compensators for multiple-input multiple-output systems, and robust, almost time-optimal controllers for double integrators with input amplitude saturations, are proposed.Windup effects are defined and anti-windup compensators aiming at minimizing the windup effects are proposed.
