1. 26. Inverse Problems in Analytic Interpolation for Robust Control and Spectral Estimation

   Författare :Johan Karlsson; Anders Lindquist; Alberto Isidori; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nevanlinna-Pick Interpolation; Approximation; Model Reduction; Robust Control; Gap-robustness; Sensitivity Shaping; Entropy functional; Spectral Estimation; Weak*-topology; Monge-Kantorovic Transportation; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : This thesis is divided into two parts. The first part deals with theNevanlinna-Pick interpolation problem, a problem which occursnaturally in several applications such as robust control, signalprocessing and circuit theory. We consider the problem of shaping andapproximating solutions to the Nevanlinna-Pick problem in a systematicway. LÄS MER

   Sammanfattning : Media streaming over the Internet is becoming increasingly popular. Currently, most media is delivered using global content-delivery networks, providing a scalable and robust client-server model. However, content delivery infrastructures are expensive. LÄS MER

5. 29. Mathematical Multi-Objective Optimization of the Tactical Allocation of Machining Resources in Functional Workshops

   Författare :Sunney Fotedar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Decision-making; Robust efficient solutions; Discrete bi-objective optimization; Capacity planning; Discrete tri-objective optimization; Production planning; Coverage gap;

   Sammanfattning : In the aerospace industry, efficient management of machining capacity is crucial to meet the required service levels to customers and to maintain control of the tied-up working capital. We introduce new multi-item , multi-level capacitated resource allocation models with a medium--to--long--term planning horizon. LÄS MER

7. 30. Control and Optimization of Fuel Cell Based Powertrain for Automotive Applications

   Författare :Qian Xun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power distribution; Cut-off frequency; Fuel cell; Chance-constraint co-design optimization; Supercapacitors; Convex programming; Electric vehicles; Load disturbance compensator; DC-link voltage; Robust co-design optimization; Batteries;

   Sammanfattning : Fuel cell powered electric vehicles, with fast-refueling time, high energy density, and zero CO2 emissions, are becoming a promising solution for future fossil-free transportation. However, the relatively slow dynamic response and the inability of recovering the regenerative energy make vehicles solely powered by fuel cells not an immediately attractive solution. LÄS MER
