1. 1. Sensorless Field-Oriented Control and Position Estimation

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Roberts Bitenieks; Lars Brander; [2023]
   Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

   Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE

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

   University essay from KTH/Mekatronik och inbyggda styrsystem

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

   Abstract : 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. READ MORE

4. 3. Study of vector control strategy on Interior Permanent Magnet Synchronous Motors

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Prabhu Bernard; [2023]
   Keywords : Direct Torque Control; IPMSM; implementation; performance;

   Abstract : This thesis presents a comprehensive study of Direct Torque Control (DTC) for Interior Permanent Magnet Synchronous Motors (IPMSMs) evaluating its potential in high performance motor drive systems. The research begins with a literature review, looking into the fundamental principles of DTC, Pulse Width Modulation (PWM), Space Vector Modulation (SVM) and Field Oriented Control (FOC). READ MORE
