1. 1. 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.

3. 2. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

   Författare :Faisal Altaf; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; converters; electrified vehicles.; model predictive control; thermal balancing; SOC balancing; battery control; Modular batteries;

   Sammanfattning : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. LÄS MER

4. 3. Fuzzy gain scheduled visual servoing for an unmanned helicopter

   Författare :Bourhane Kadmiry; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linkoping University is the development of an intelligent command and control system, containing active-vision sensors, which supports the operation of an unmanned air vehicle (UAV). One of the UA V platforms of choice is the R5O unmanned helicopter, by Yamaha. LÄS MER

5. 4. On motion planning and control for truck and trailer systems

   Författare :Oskar Ljungqvist; Daniel Axehill; Johan Löfberg; Jonas Mårtensson; Linköpings universitet; []
