Sensorless Control of Dual Three-Phase IPMSM Based on Frequency Adaptive Linear Extended State Observer [PDF]
IEEE Transactions on Power Electronics, 2023 The sensorless control of interior permanent magnet synchronous motor (IPMSM) based on the conventional linear extended state observer (LESO) does not have sufficient capability to eliminate the steady-state position estimation error. To solve this issue,
