Flux-Weakening (F-W) based on feedback voltage regulation is commonly adopted in Interior Permanent Magnet Synchronous Motor (IPMSM) drive systems. Voltage vector magnitude is controlled in closed-loop by modifying the current reference space vector, following a reference value related to the inverter limitations. Stable and fast voltage control allows to operate with lower voltage margin, which leads...
Maximum Torque Per Ampere (MTPA) tracking techniques for the control of Interior Permanent Magnet Synchronous Machines (IPMSMs) and Synchronous Reluctance Machine (SynRMs) drives were introduced in the last decade, with the aim of overcoming the dependence on motor parameter knowledge accuracy. In fact, uncertainty due to identification errors, magnetic saturation or temperature variation results...
Maximum Torque Per Ampere (MTPA) based on motor parameters is a common approach to achieve high efficiency and torque density in Interior Permanent Magnet Synchronous Machine Drives (IPMSMs). However, uncertainty (e.g., due to identification errors, magnetic saturation, or temperature variation) results in undesired deviation from the optimal operating trajectory. To solve this problem, MTPA tracking...
