A second-order generalized integrator-linear extended state observer for sensorless control of permanent magnet synchronous motor

The high-frequency (HF) signal injection method is widely used in sensorless control of permanent magnet synchronous motors (PMSMs). Conventional strategies typically integrate a band-pass filter (BPF) with a phase-locked loop (PLL) to extract HF current
