一种用于永磁同步电机速度-磁链变换模型的高阶非线性自适应观测器：一种PMSM无传感器控制方案

This article presents a novel speed-flux transformation model, derived from the traditional active flux model of permanent magnet synchronous motor, which features a known regression term of speed. This advancement achieves nonlinear parameterization of motor speed, enabling the construction of a speed adaptive observer. Then, a high order nonlinear adaptive (HONA) observer is developed by adoptin...
