1. 16. 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

3. 17. Automation and traction control of articulated vehicles

   Författare :Ulf Andersson; Vladimir Vantsevich; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : Articulated machines such as load-haul-dump machines, wheel loaders and haulers operate in many different environments and driving conditions. In particular they need to be able to perform well with road conditions and loads that can change drastically, setting hard requirements on performances and robustness. LÄS MER

4. 18. Wireless Sensor Network Scheduling and Event-based Control for Industrial Processes

   Författare :Takuya Iwaki; Karl H. Johansson; Vijay Gupta; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; Wireless sensor and actuator network; Event-based control; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Control over wireless sensor and actuator networks is of growing interest in process industry since it enables flexible design, deployment, operation, and maintenance. An important problem in industrial wireless control is how to limit the amount of information that needs to be exchanged over the network. LÄS MER

5. 19. Nonlinear System Identification and Control Applied to Selective Catalytic Reduction Systems

   Författare :Soma Tayamon; Bengt Carlsson; Torbjörn Wigren; Bo Egardt; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear identification; nonlinear control; selective catalytic reduction; NOx reduction; recursive prediction error method; feedback linearisation; multiple-model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : The stringent regulations of emission levels from heavy duty vehicles create a demand for new methods for reducing harmful emissions from diesel engines. This thesis deals with the modelling of the nitrogen oxide (NOx) emissions from heavy duty vehicles using a selective catalyst as an aftertreatment system, utilising ammonia (NH3) for its reduction.

7. 20. Topics in Modeling, Control, and Implementation in Automotive Systems

   Författare :Magnus Gäfvert; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Sammanfattning : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. LÄS MER
