  1. 6. 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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gianmarco Grandi; [2023]
    Keywords : 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;

    Abstract : 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.
