    Abstract : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters. READ MORE

  3. 2. Physics-Informed Deep Learning for System Identification of Autonomous Underwater Vehicles : A Lagrangian Neural Network Approach

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

    Author : Badi Mirzai; [2021]
    Keywords : AUV; System Identification; Deep Learning; Physics-Informed Deep Learning; Lagrangian Neural Networks; AUV; System Identifiering; Djupinlärning; Fysik-Informerad Djupinlärning; Lagrangianska Neurala Nätverk;

    Abstract : In this thesis, we explore Lagrangian Neural Networks (LNNs) for system identification of Autonomous Underwater Vehicles (AUVs) with 6 degrees of freedom. One of the main challenges of AUVs is that they have limited wireless communication and navigation under water. READ MORE

  4. 3. State- and Parameter Estimation for Spacecraft with Flexible Appendages using Unscented Kalman Filters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Andrea Mosquera Alonso; [2019]
    Keywords : Estimation; flexibility; flexible spacecraft; spacecraft; kalman filter; unscented Kalman filter; spacecraft dynamics; flexible dynamics;

    Abstract : The problem of system identification for dynamic effects on spacecraft has become increasingly relevant with the surge of agile spacecraft, which must perform large amplitude maneuvers at high rates. Precise knowledge of the state of the spacecraft, as well as of the parameters characterizing its motion, is vital for the design of control algorithms enabling stabilization and pointing accuracy.

  5. 4. Dynamic Model of a Hydraulic Servo System for a Manipulator Robot

    University essay from KTH/Elektrisk energiomvandling

    Author : Yalcin Efe; [2014]
    Keywords : ;

    Abstract : In this master thesis, a mathematical model of a hydraulic servo system for a manipulator robot is completed by using several different methodologies. The models proposed are particularly tuned for the DeLaval VMS robotic arm. READ MORE

  6. 5. Modelling and Control System Design to control Water temperature in Heat Pump

    University essay from Avdelningen för fysik och elektroteknik

    Author : Md Abdul Salam; Md Mafizul Islam; [2013]
    Keywords : Electrical; Control System; System Identification;

    Abstract : The thesis has been conducted at Hetvägg AB and the aim is to develop a combined PID and Model Predictive Controller (MPC) controller for an air to water heat pump system that supplies domestic hot water (DHW) to the users. The current control system is PLC based but because of its big size and expensive maintenance it must be replaced with a robust controller for the heat pump. READ MORE
