  1. 1. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer

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

    Author : Elvira Niemelä; [2022]
    Keywords : Permanent Magnet Synchronous Machine; Permanent Magnet Temperature Estimation; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer; Permanentmagnetiserad Synkronmaskin; Temperaturestimering för Permanentmagneter; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer;

    Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

  3. 2. 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.

  4. 3. Lifetime estimation of lithium-ion batteries for stationary energy storage system

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Joakim Andersson; [2017]
    Keywords : Li-ion battery; State of charge; State of health; Kalman filtering; Energy Storage;

    Abstract : With the continuing transition to renewable inherently intermittent energy sources like solar- and wind power, electrical energy storage will become progressively more important to manage energy production and demand. A key technology in this area is Li-ion batteries. READ MORE

  5. 4. Cooperative localization using foot-mounted inertial navigation and ultrawideband ranging : a simulation study

    University essay from Uppsala universitet/Signaler och System

    Author : Fredrik Olsson; [2014]
    Keywords : ;

    Abstract : This report aims to evaluate the performance gains that can be obtained by introducing cooperative localization in an indoor firefighter localization system, through the use of scenario-based simulations. Robust and accurate indoor localization for firefighters is a problem that is not yet resolved. READ MORE
