  1. 21. Online trajectory planning and observer based control

    Författare :David A. Anisi; Xiaoming Hu; Daizhan Cheng; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Consensus Problem; Simultaneous Arrival; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : The main body of this thesis consists of four appended papers. The first two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

    Sammanfattning : A large proportion of movement in urban area is constrained to a road network such as pedestrian, bicycle and vehicle. That movement information is commonly collected by Global Positioning System (GPS) sensor, which has generated large collections of trajectories. LÄS MER

  5. 24. Attitude and Trajectory Estimation for Small Suborbital Payloads
