  1. 1. Feedback Linearization for Model Agnostic Aircraft Simulation Control

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

    Författare :Fredrik Horn; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis presents a method, based on feedback linearization, for controlling a general 3-degree-of-freedom simulation model of an aircraft. Only aircraft models that utilize Taylor approximations of the aerodynamic coefficients are considered. LÄS MER

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonatan Gustafsson; [2021]
    Nyckelord :MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

    Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER

  4. 3. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

    Master-uppsats, KTH/Rymdteknik

    Författare :Hasan Basaran; [2020]
    Nyckelord :Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

    Sammanfattning : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.

  5. 4. Nonlinear Attitude Control ofa Generic Aircraft

    Master-uppsats, KTH/Flygdynamik

    Författare :Mir Shwan Kurdi; [2019]
    Nyckelord :;

    Sammanfattning : Determining suitable controllers for the process of evaluating dynamic per-formance of multiple versions of an aircraft’s aerodynamical, geometric and propulsive properties in its conceptual stage is an expensive task.In this report a proposition is made to utilize a generalized feedback lin-earizing controller that o˙ers the aircraft designer valuable insight into the manoeuvre performance of their aircraft.

  7. 5. Cooperative Transportation of Mobile Manipulators With Collision Avoidance

    Master-uppsats, KTH/Reglerteknik

    Författare :Yu Wang; [2018]
    Nyckelord :;

    Sammanfattning : In this work, we propose two Nonlinear Model Predictive Control(NMPC) schemes, Decentralized Nonlinear Model Predictive Control(DNMPC) and Centralized Nonlinear Model Predictive Control (CNMPC),for cooperative transportation of an object, which is rigidlygrasped by N agents. We use feedback linearization and model reductionto reduce overall complexity of the model. LÄS MER
