  1. 1. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Qinglong He; [2022]
    Nyckelord :Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

    Sammanfattning : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. LÄS MER

  3. 2. Predictive Energy Management of Long-Haul Hybrid Trucks : Using Quadratic Programming and Branch-and-Bound

    Master-uppsats, Linköpings universitet/Fordonssystem

    Nyckelord :Predictive energy management; quadratic programming; branch-and-bound; mixed-integer quadratic programming; energy optimization; look-ahead control; model predictive control; receding horizon control; optimal control; convex optimization; heavy-duty vehicle; long-haul truck; hybrid electric vehicle;

    Sammanfattning : This thesis presents a predictive energy management controller for long-haul hybrid trucks. In a receding horizon control framework, the vehicle speed reference, battery energy reference, and engine on/off decision are optimized over a prediction horizon. LÄS MER

  4. 3. Quadratic Programming Models in Strategic Sourcing Optimization

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Ahlbom; [2017]
    Nyckelord :;

    Sammanfattning : Strategic sourcing allows for optimizing purchases on a large scale.Depending on the requirements of the client and the offers provided forthem, finding an optimal or even a near-optimal solution can become computationally hard. LÄS MER

  5. 4. Using ADMM for Hybrid System MPC

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Mattias Fält; Lucas Jimbergsson; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Model Predictive control (MPC) has been studied extensively because of its ability to handle constraints and its great properties in terms of stability and performance [Mayne et al., 2000]. We have in this thesis focused on MPC of Hybrid Systems, i.e. LÄS MER
