N2 - A hybrid sensorless control system for the ironless flywheel machine based on I-F startup strategy and improved full-order sliding mode observer (FSMO) is proposed in this paper. I-F startup method is adopted for the low-speed sensorless control, and the improved FSMO is appropriate for the medium and high speed. In this paper, the principle and dynamic process of I-F startup is analyzed firstly. Then, the FSMO and sinusoidal switching function are carried out using stator current and back electromotive force as state variables, and the estimated rotor position and speed are got through the phase-locked loop. Compared with the traditional sliding mode observer, this method has the advantages of reducing phase delay, weakening system chattering and improving the accuracy of position calculation. Furthermore, the dynamic switching technology is studied and the smooth transition between the two sensorless control methods is achieved. Finally, the effectiveness of the proposed method is verified.
