• Controlled Lagrangian Particle Tracking Error Under Biased Flow Prediction 

      Szwaykowska, Klementyna; Zhang, Fumin (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013)
      In this paper we model the controlled Lagrangian particle tracking (CLPT) error for marine vehicles moving in an ocean flow field, with guidance from ocean models. We linearize the error about the nominal modeled ...
    • A Lower Bound for Controlled Lagrangian Particle Tracking Error 

      Szwaykowska, Klementyna; Zhang, Fumin (Georgia Institute of Technology, 2010-12)
      Autonomous underwater vehicles are flexible mobile platforms for ocean sampling and surveillance missions. However, navigation of these vehicles in unstructured, highly variable ocean environments poses a significant ...
    • Task Scheduling for Control Oriented Requirements for Cyber-Physical Systems 

      Zhang, Fumin; Szwaykowska, Klementyna; Wolf, Wayne; Mooney, Vincent (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-12)
      The wide applications of cyber-physical systems (CPS) call for effective design strategies that optimize the performance of both computing units and physical plants. We study the task scheduling problem for a class of ...
    • Trend and Bounds for Error Growth in Controlled Lagrangian Particle Tracking 

      Szwaykowska, Klementyna; Zhang, Fumin (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-12-18)
      This paper establishes the method of controlled Lagrangian particle tracking (CLPT) to analyse the offsets between physical positions of marine robots in the ocean and simulated positions of controlled particles in an ...
