The fourth order flux observer with in‐loop filter for permanent magnet synchronous motor sensorless control by Ziwen Wang, Ciyong Luo, Xiaoshu Jia, Zihao Xing

“…To dispose these issues, an improved non‐linear flux observer (FOIFFO) using a second‐order generalised integrator as an in‐loop filter is proposed for the sensorless control of permanent magnet synchronous motors. The observer demonstrates robust performance in eliminating DC bias and having a strong filtering ability for high‐order harmonics even without amplitude and phase compensation to accurately estimate the rotational speed and rotor position. …”
