Abstract
Maksimalt moment pr. ampere (MTPA) styring hjælper elmotorer med at levere mest muligt moment for hver strøm-enhed og dermed øge effektiviteten. Dette speciale undersøger og analyserer on-line (realtids) MTPA-sporingsteknikker for to udbredte typer synkrone permanentmagnetmaskiner: Surface Mounted Permanent Magnet Synchronous Machine (SPMSM), hvor magneterne er monteret på rotorens overflade, og Interior Permanent Magnet Synchronous Machine (IPMSM), hvor magneterne er indbygget i rotoren. Den udvalgte sporingsteknik afprøves på både SPMSM- og IPMSM-platforme. Ydelsen vurderes under forskellige driftsforhold med fokus på sporingsnøjagtighed, pålidelighed og reaktionsevne under pludselige ændringer (transienter).
Maximum Torque Per Ampere (MTPA) control helps electric motors produce the most torque for each unit of current, improving efficiency. This thesis studies and analyzes on-line (real-time) MTPA tracking techniques for two common permanent-magnet motor types: Surface-Mounted Permanent Magnet Synchronous Machines (SPMSM), where magnets are on the rotor surface, and Interior Permanent Magnet Synchronous Machines (IPMSM), where magnets are embedded inside the rotor. The candidate tracking technique is implemented and tested on both SPMSM and IPMSM platforms. Performance is evaluated under different operating conditions, focusing on tracking accuracy, reliability, and how quickly it responds during sudden changes (transients).
