  1. 26. Optimization-Based Motion Planning and Model Predictive Control for Autonomous Driving : With Experimental Evaluation on a Heavy-Duty Construction Truck

    Författare :Pedro F. Lima; Bo Wahlberg; Paolo Falcone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Autonomous Driving; Model Predictive Control; Motion Planning; Optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis addresses smooth motion planning and path following control of autonomous large and heavy industrial vehicles, such as trucks and buses, using optimization-based techniques. Autonomous driving is a rapidly expanding technology that promises to play an important role in future society, since it aims at more energy efficient, more convenient, and safer transport systems.

  3. 27. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

    Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
    Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER

  4. 28. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

    Författare :Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

    Sammanfattning : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.

  5. 29. Computationally efficient exact remodeling of optimization programs with applications to autonomous driving

    Författare :Johan Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous driving; Real-time implementation; Model predictive control; Convex optimization;

    Sammanfattning : The future of autonomous vehicles is rapidly approaching and the published and available research, both from vehicle manufacturers and universities, is abundant. This new technology promises less pollution, lower accident rates, decreased congestion and the possibility to relax or work while a vehicle takes you where you need to go. 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
