要約(英語): In this paper, a position sensorless control method for IPMSMs using a full-order observer based on an algebraic design is proposed. The full-order observer is well known to be one of the powerful estimators for sensorless control of AC motors, for which design strategies have already been discussed. Although many numerical design and heuristic design approaches have been proposed so far, the design formulation for improving robustness with respect to mismatches in some parameters, however, is now an open problem. First, the proposed flux model for position sensorless control of IPMSMs has been reviewed, in which this model can approximately estimate the maximum torque control (MTC) frame, which stands for a new coordinate aligned with the current vector at the MTPA control. Next, an algebraic design of the full-order observer based on the proposed flux model has been proposed. In this paper, a design guideline to suppress the sensitivity of the speed estimation error has also been proposed. Finally, some experimental results demonstrate the effectiveness of the proposed method.
