1. 1. On Modeling and Stability Analysis of Grid-Connected Voltage Source Converters

   Författare :Hongyang Zhang; Stefan Östlund; Xiaoming Yuan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-inertia grid; multiple-input multiple-output MIMO ; single-input single-output SISO ; small-signal model; stability analysis; voltage source converters VSCs ; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With increasing deployment of voltage source converters (VSCs) in the grid, instability phenomena due to converter--grid interactions have been observed. Modeling and stability analysis of grid-connected VSCs have become popular research topics. LÄS MER

3. 2. Interaction Analysis in Multivariable Control Systems : Applications to Bioreactors for Nitrogen Removal

   Författare :Björn Halvarsson; Bengt Carlsson; Elling Jacobsen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; biological nitrogen removal; bioreactor models; control structure design; cost-efficient operation; decentralized control; interaction measures; minimum variance control; multivariable control; wastewater treatment; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Many control systems of practical importance are multivariable. In such systems, each manipulated variable (input signal) may affect several controlled variables (output signals) causing interaction between the input/output loops. LÄS MER

4. 3. On Feedforward Adaptation

   Författare :Magnus Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; feedforward; adaptive;

   Sammanfattning : Adaptation of a feedforward term in a two-degrees-of-freedom servo controller for single-input single-output systems is investigated in this thesis. The first part ofthe thesis gives a clarifying analysis of feedback-error learning in a linear and time-invariant framework. LÄS MER

5. 4. Glycemic Control and Temperature Control in Buildings

   Författare :Meike Stemmann; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes; Prediction; Optimization; Decision Support System; Inverted Decoupling; PID; Buildings; Ventilation System;

   Sammanfattning : This thesis consists of two parts, applying concepts from automatic control to different application areas.The first part of this thesis concerns the development of an optimization-based algorithm, determining the size of insulin and glucose doses for patients suffering from Diabetes Mellitus and treated with multiple insulin injections.

7. 5. Logic-based switching control of nonlinear systems using high-gain observers

   Författare :Leonid Freidovich; Hassan K. Khalil; Michigan State University; []
   Nyckelord :;

   Sammanfattning : The design of robust output and state feedback controllers for practical track-ing and stabilization for nonlinear systems with large-scale parametric uncertainty is considered. We consider a class of single-input single-output systems that can be transformed into a special form, where unavailable states (if any) are derivatives of the measured outputs. LÄS MER
