  1. 1. Real-time Model Predictive Control with Complexity Guarantees Applied on a Truck and Trailer System

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Edvin Bourelius; [2022]
    Nyckelord :Real-time; Model Predictive Control; Quadratic Programing; Active-set method; Complexity Certification; Truck; Trailer;

    Sammanfattning : In model predictive control an optimization problem is solved in every time step, which in real-time applications has to be solved within a limited time frame. When applied on embedded hardware in fast changing systems it is important to use efficient solvers and crucial to guarantee that the optimization problem can be solved within the time frame.

  3. 2. Preconditioned iterative methods for PDE-constrained optimization problems with pointwise state constraints

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Anders Ström; [2017]
    Nyckelord :;

    Sammanfattning : Optimization problems constrained by partial differential equations (PDEs) arise in a variety of fields when one wants to optimize a system governed by a PDE. The goal is to compute a control variable such that a state variable is as close as possible to some desired state when control and state are coupled by some PDE. LÄS MER

  4. 3. Study of early termination of MPC Algorithms

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

    Författare :Gustav Henriks; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With a steady development of technology, the use of Model Predictive Control (MPC) has become more and more popular since the computation time has gone down. With this increase, a need for determining which MPC algorithm is good for solving a certain type of MPC problem has occurred which would facilitate the choice of algorithm and also could increase the performance.

  5. 4. Erfarenheter från utveckling av kvadratisk optimeringsalgoritm för prediktionsreglering

    Kandidat-uppsats, Linköpings universitet/Programvara och system; Linköpings universitet/Tekniska fakulteten

    Författare :Dennis Ljung; Ruben Das; Johan Isaksson; Alexander Yngve; Adam Sestorp; Martin Söderén; Sebastian Fast; [2015]
    Nyckelord :prediktionsreglering programmering active set method;

    Sammanfattning : Denna kandidatrapport studerar en projektuppgift som har utförts av en grupp studenter på Linköpings universitet. Uppgiften har givits av en industridoktorand på Saab och härstammar från reglering av styrsystem i stridsflygplan. Det som har tagits fram av kandidatgruppen är en kvadratisk optimeringslösare som även kan köras från MATLAB. LÄS MER

  7. 5. Peak to Average Ratio Reduction in Wireless OFDM Communication Systems

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :KAMRAN HAIDER; [2006]
    Nyckelord :PAR; OFDM; Active-Set; Tone reservation; PSD constraint;

    Sammanfattning : Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today’s cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. LÄS MER
