“…Energy storage technology is widely used to reduce the impact of distributed energy, such as wind power and photovoltaic, on the power grid. As a new physical energy storage device in recent years, the flywheel energy storage system uses the kinetic energy of a high-speed rotating body for energy storage and realizes the conversion of electric energy and kinetic energy by controlling the flywheel speed [1][2][3]. Compared with chemical energy storage, flywheel energy storage has high efficiency, long life, high safety, pollution-free, and so on [4][5].…”

Aiming at the error problem in estimating the speed of a permanent magnet synchronous motor(PMSM) using a sliding mode observer in a flywheel energy storage system, a super twist sliding mode observer(SMO) is used to replace the traditional sliding mode observer. A new saturation function is designed to replace the sign function. In addition, a constant sliding mode gain may lead to a decrease in observation accuracy during speed switching. An adaptive sliding mode gain is proposed to reduce chattering, The accurate estimation of the comprehensive speed range observer is enhanced, and the stability of the proposed observer is proved. On this basis, a super twist sliding mode speed controller is designed to replace the traditional PI controller to improve the observation performance of the system. The flywheel energy storage system's simulation model is built, and the flywheel energy storage system's constant speed standby and charging conditions are simulated. The simulation results verify the correctness and effectiveness of the improved super twist sliding mode observer in the flywheel motor.
