提出了一种基于代数设计的全阶观测器的IPMSM无位置传感器控制方法。众所周知，全阶观测器是交流电机无传感器控制的强大估计器之一，其设计策略已经讨论过。虽然许多数值设计和启发式设计方法已被提出到目前为止，提高鲁棒性方面的一些参数的不匹配的设计公式，但是，现在是一个开放的问题。首先，所提出的磁链模型的IPMSM的无位置传感器控制已被审查，在该模型中，可以近似估计的最大转矩控制（MTC）框架，这代表了一个新的坐标与当前矢量对准的MTPA控制。其次，提出了基于磁链模型的全阶观测器的代数设计方法。在本文中，还提出了一个设计准则，以抑制速度估计误差的敏感性。最后通过实验验证了该方法的有效性。
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.
