1. 1. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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

   Author : Erik Lindberg; [2023]
   Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

   Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps.

3. 2. Online parameter estimation in electric motors

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Abizar Sadikot; [2021]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. AT-HARM10 vs. OPERAM DRA Adjudication Guide - Assessment of Medication Related Hospital Admissions

   University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Author : Anton Hedman; [2020]
   Keywords : AT-HARM10; OPERAM;

   Abstract : Background: Medication related admissions (MRAs) account for a substantial amount of all hospital admissions and most MRAs are considered preventable. In order to reduce the amount of MRAs, comprehensive medication reviews performed by clinical pharmacists on hospitalised patients could be a viable strategy. READ MORE

5. 4. External validation of a tool to assess medication-related admissions in four Swedish hospitals

   University essay from Uppsala universitet/Avdelningen för farmakokinetik och läkemedelsterapi

   Author : Filip Nacke; [2019]
   Keywords : ;

   Abstract : External validation of a tool to assess medication-related admissions in four Swedish hospitals Background The MedBridge trial is a large ongoing clinical trial on medication reviews in elderly patients in Sweden with participating hospitals from Uppsala, Enköping, Västerås and Gävle. A tool for assessing medication-related admissions (MRAs) has been developed and validated in Uppsala: Assessment Tool for identifying Hospital Admissions Related to Medications (AT-HARM10).

6. 5. Parameter Estimation in a Permanent Magnet Synchronous Motor

   University essay from Reglerteknik

   Author : Mikael Tenerz; [2011]
   Keywords : Permanet magnet synchronous motor parameter estimation;

   Abstract : This thesis adresses the problem of estimating the parameters in a permanent magnet synchronous motor (PMSM). There is an uncertainty about the parameters, due to age and tolerances in the manufacturing process. Parameters such as the resistance and the current to torque factor Kt, changes with respect to temperature as well. READ MORE
