2. 1. Systematic Design of Linear Feedback Amplifiers

   Author : Martin Lantz; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Volterra series; dynamic distortion; clipping; nonlinear distortion; systematic design; feedback amplifier; Signalbehandling;

   Abstract : This work adds a quantitative description of distortion to the structured design method of negative-feedback amplifiers. It constitutes a power-series representation of the feedback amplifier, which may include dynamic (memory) effects, where the design parameters appear explicitly. READ MORE

4. 2. Analytic Parameterization of Stabilizing Controllers for the Moore-Greitzer Compressor Model

   Author : Alina Andersson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear control; Moore-Greitzer compressor model; Dynamic output feedback; Compressors; Nonlinear control systems; Stability robustness; Constraints; Nonlinearity; Lyapunov stability;

   Abstract : This work presents an extension, simplification and application of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints (QC). Our method was motivated by the challenges of output feedback control design for the three-state Moore-Greitzer (MG) compressor model. READ MORE

5. 3. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

   Author : Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

   Abstract : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. READ MORE

6. 4. Stealthy Sensor Attacks on Feedback Systems : Attack Analysis and Detector-based Defense Mechanisms

   Author : David Umsonst; Henrik Sandberg; Hideaki Ishii; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis, we investigate sensor attacks on feedback systems and how anomaly detectors can be used as a defense mechanism. We consider an attacker with access to all sensor measurements and full knowledge about the closed-loop system model. READ MORE

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

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

   Abstract : 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. READ MORE
