摘要
Systems and methods for robust control of a sensorless interior permanent magnet synchronous motor during severe operating conditions that causes motor parameter variation. A multi-model flux observer and a dynamic direct flux motor controller act in concert to generate driving commands. The flux observer transitions between providing flux-based rotor characteristic estimates based on different motor models. DHFI filtered currents can be utilized to obtain flux-based characteristic estimates using a motor magnetic model that are unaffected by motor parameter variations. The multi-model flux observer can be configured to transition between suitable estimation methods to reduce, minimize, or eliminate the effects of motor parameter variations.
