In this paper, a method is proposed to improve the performance of a mechanical transducer-less control of an interior permanent magnet synchronous machine (IPMSM) with use of a dedicated online parameter estimator (OPE). The active flux observer is employed for position estimation, along with the proposed OPE which displays high sensitivity to parameter-discrepancies, that its parameter adaptation algorithm (PAA) takes advantage of. The temperature-sensitive parameters are adapted in different speed ranges by scheduling the adaptation-gains for optimal performance. The simulation results show that the proposed method improves the torque and speed control of the drive across the torque-speed plane particularly in the presence of varying parameters.
