   Sammanfattning : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. LÄS MER

3. 2. Input-Output Stability Analysis of Networked Control Systems

   Författare :Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). LÄS MER

   Sammanfattning : Monetary Policy and Macroprudential Regulations. We investigate the desirability of macroprudential regulations in a DSGE model with collateral and income borrowing constraints. LÄS MER

5. 4. Control of Constrained Dynamical Systems with Performance Guarantees: With Application to Vehicle motion Control

   Författare :Ankit Gupta; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear matrix inequalities; Robust control; Invariant set; Semi-definite program; Linear parameter varying system; Linear fractional transformation;

   Sammanfattning : In control engineering, models of the system are commonly used for controller design. A standard control design problem consists of steering the given system output (or states) towards a predefined reference. Such a problem can be solved by employing feedback control strategies.

7. 5. Feedback Control and Sensor Fusion of Vision and Force

   Författare :Tomas Olsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor based robot control; Visual tracking; visual servoing; resource optimization; Kalman filter;

   Sammanfattning : This thesis deals with feedback control using two different sensor types, force sensors and cameras. In many tasks robotics compliance is required in order to avoid damage to the workpiece. Force and vision are the most useful sensing capabilities for a robot system operating in an unknown or uncalibrated environment. LÄS MER
