   Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Capacitive body coupled communication (BCC), frequency range 500 kHz to 15 MHz, is considered an emerging alternate short range wireless technology which can meet the stringent low power consumption (< 1 mW) and low data rate (< 100 kbps) requirements for the next generation of connected devices for applications like internet-of-things (IoT) and wireless sensor network (WSN). But a reliable solution for this mode of communication covering all possible body positions and maximum communication distances around the human body could not be presented so far, despite its inception around 20 years back in 1995.

4. 48. A Harmonic-Oscillator Design Methodology Based on Describing Functions

   Författare :Jesper Bank; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator design efficiency; phase noise; impulse sensitivity function; design methodology; amplitude control; frequency tuning; oscillator; describing function;

   Sammanfattning : Oscillators are present in most electronic equipment where they provide timing information, for example as sampling clocks in analog-to-digital converters or as radio carriers in wireless communications. To design an oscillator, we must have knowledge of the properties and the operation of oscillators. LÄS MER

5. 49. On Application Oriented Experiment Design for Closed-loop System Identification

   Författare :Afrooz Ebadat; Bo Wahlberg; Torsten Söderström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; closed-loop identification; experiment design for identification;

   Sammanfattning : System identification concerns how to construct mathematical models of dynamic systems based on experimental data. A very important application of system identification is in model-based control design. In such applications it is often possible to externally excite the system during the data collection experiment. LÄS MER

7. 50. Gain-Scheduled Controller Design

   Författare :Adrian Ilka; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Guaranteed cost control; Gain-scheduled control; Bellman-Lyapunov function; Lyapunov theory of stability; Robust control; Input output constraints; LPV system;

   Sammanfattning : This thesis is devoted to controller synthesis, i.e. to finding a systematic procedure to determine the optimal (sub-optimal) controller parameters which guarantees the closed-loop stability and guaranteed cost for uncertain nonlinear systems with considering input/output constraints, all this without on-line optimization.
