  3. 2. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

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

    Författare :Gianmarco Grandi; [2023]
    Nyckelord :LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

    Sammanfattning : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

  4. 3. Path Planning and Path Following for an Autonomous GPR Survey Robot

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Maurice Meedendorp; [2022]
    Nyckelord :robotics; gpr; autonomous; robot; ros; slam; path follow; path plan; obstacle avoidance;

    Sammanfattning : Ground Penetrating Radar (GPR) is a tool for mapping the subsurface in a non-invasive way. GPR surveys are currently carried out manually; a time-consuming, tedious and sometimes dangerous task. This report presents the high-level software components for an autonomous unmanned ground vehicle to conduct GPR surveys. LÄS MER

  5. 4. Autonomously docking, using object detection, and path planning

    Master-uppsats, KTH/Mekatronik

    Författare :Joel Bergman; [2021]
    Nyckelord :;

    Sammanfattning : With today’s climate change Volvo Construction Equipment (CE) must develop machines that emit less carbon dioxide or no carbon dioxide at all. One way to go is to electrify their machines. Volvo CE has developed an autonomous electric machine called HX02. Today the HX02 is charged with an inverted pantograph. LÄS MER

  7. 5. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jacob Wallersköld; Johan Appelros; [2021]
    Nyckelord :wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

    Sammanfattning : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. LÄS MER
