1. 1. Online parameter estimation in electric motors

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Abizar Sadikot; [2021]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. LÄS MER

3. 2. Torque-Based Load Estimation for Passenger Vehicles

   Nyckelord :Load Estimation; RLS; Recursive least squares; torque; torque-based; mass estimation; mass; passenger vehicle; estimation algorithm; load estimation algorithm; forgetting factor; RLS with forgetting factor;

   Sammanfattning : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. LÄS MER

4. 3. Robust On-Line Estimation

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Lars Gustafsson; Mikael Olsson; [1999]
   Nyckelord :Technology and Engineering;

   Sammanfattning : In the presence if poor excitation and abrupt changes of a time-varying system the Recursive least square (RLS) with forgetting factor is not able to track the parameters in a suitable way. The purpose of this thesis is to investigate different kinds of proposals of algorithms to deal with the phenomenons arising, such as estimator windup or too slow convergence of the estimations.
