1. 1. PID control of TITO systems

   Författare :Pontus Nordfeldt; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; PID Control; Linear Systems; Process Control; Multi-variable Control;

   Sammanfattning : This thesis treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. LÄS MER

4. 3. CPU Resource Management and Noise Filtering for PID Control

   Författare :Vanessa Romero Segovia; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; embedded systems; real-time systems; multimedia; multicore; measurement noise; filtering; trade-offs; robustness; performance; SDU; noise gain; PID control;

   Sammanfattning : The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. LÄS MER

5. 4. PID Control, Design, Extension, Application

   Författare :Helene Panagopoulos; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; PID control. Design. Optimization. Load disturbance rejection. Measurement noise filtering. Set point response. Robustness. Sensitivity. H-infinity control. Undamped process modes. Active control. Allpass and bandpass filter. Evaluation. Steam generator. Pulp and paper.; robotics; Automation; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. LÄS MER

7. 5. Friction Stir Welding of Copper Canisters Using Power and Temperature Control

   Författare :Lars Cederqvist; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; copper; temperature control; PID control;

   Sammanfattning : This thesis presents the development to reliably seal 50 mm thick copper canisters containing the Swedish nuclear waste using friction stir welding. To avoid defects and welding tool fractures, it is important to control the tool temperature within a process window of approximately 790 to 910°C. LÄS MER
