1. 1. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   Master-uppsats, KTH/Mekatronik och inbyggda styrsystem

   Författare :Arvid Bergvall; Pontus Lundman; [2023]
   Nyckelord :Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Sammanfattning : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. LÄS MER

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Erik Lindberg; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Reference Tracking with Adversarial Adaptive Output- Feedback Model Predictive Control

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Linda Bui; [2021]
   Nyckelord :Model Predictive Control; Adversarial Multi-Armed Bandits; Kalman Filter; Output-Feedback; Adaptive Control ; Modell Prediktiv Reglering; Kontradiktoriska Flerarmade Banditer; Kalman Filter; Output-Feedback; Adaptiv Reglering;

   Sammanfattning : Model Predictive Control (MPC) is a control strategy based on optimization that handles system constraints explicitly, making it a popular feedback control method in real industrial processes. However, designing this control policy is an expensive operation since an explicit model of the process is required when re-tuning the controller. LÄS MER

5. 4. 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

7. 5. Fostering Anticipatory Action via Social Protection Systems : A Case Study of the Climate Vulnerability of Flood-Exposed Social Security Allowance Beneficiaries in Bardiya District, Nepal

   Master-uppsats, Uppsala universitet/Teologiska institutionen

   Författare :Sabrina Desroches; [2020]
   Nyckelord :Climate disaster; climate vulnerability; climate resilience; social protection; Shock Responsive Social Protection; Adaptive Social Protection; Early Warning Systems; Forecast-based Financing; Floods; Nepal;

   Sammanfattning : Rationale – Climate disasters represent a significant and growing proportion of the humanitarian burden and are a key factor in increasing poverty and insecurity. A myriad of studies demonstrate that aid delivered in an ex-ante fashion can be effective in mitigating losses of life, assets and livelihoods associated with climate hazards. LÄS MER
