提出了一种既能实现最大每安培扭矩控制又能实现内置式永磁同步电机无位置传感器控制的磁链模型。针对观测器误差方程阶数为四阶、极点配置困难的情况，提出了用全阶观测器估计磁链，并给出了全阶观测器的极点配置方法。这种全阶观测器的极点配置是通过求解一个γ正实问题和一个H-∞控制问题得到的，在这种情况下，可以对速度估计误差进行鲁棒磁链估计。在此，IPMSM无位置传感器控制的实验结果表明，所提出的全阶观测器极点配置是非常有用的，可以用来实现Mtpa控制。
A flux model that can easily achieve both maximum torque per ampere (MTPA) control and position sensorless control of interior permanent magnet synchronous motors (IPMSMs), is proposed herein. Flux is proposed to be estimated using a full-order observer whose pole assignment is difficult because the order of the error equations of the observer becomes four, and the pole assignment of the full-order observer is proposed. This pole assignment of the full-order observer, in which robust flux estimation against velocity estimation error become possible, is obtained by solving a γ-positive real problem and a H∞ control problem. Herein, the experimental result of the position sensorless control of IPMSMs indicates that the proposed pole assignment of the full-order observer is highly useful and can be used to realize MTPA control.
