基于全阶滑模观测器和前馈正交锁相环的带LC正弦滤波器的IPMSM无传感器控制

A position sensorless control of interior permanent synchronous motor (IPMSM) equipped with LC sinusoidal filter based on the full-order sliding mode observer (FOSMO) and feedforward quadrature phase-locked loop (FQPLL) is proposed in this article. The FOSMO is designed to estimate stator currents, stator voltages, and extended back electromotive forces of IPMSM. To enhance the rapidity of the con...
