Abstract
In order to mitigate the bus voltage fluctuations in flywheel energy storage system during operational mode transition
an improved active disturbance rejection control strategy based on a cascade extended state observer was proposed. The conventional voltage-current loop control was integrated into a single voltage loop control
and the total disturbance experienced by the system during operational mode transition was introduced as a new state variable. A cascade extended state observer was designed to observe and compensate for the control quantity with the new state variable. By implementing real-time observation and compensation of the disturbance
the contradiction between the rapid response and overshoot characteristics of traditional PI control was mitigated. Results show that the proposed strategy significantly enhances the voltage regulation performance during various operational mode transitions compared with conventional active disturbance rejection control. The transition from test operation to charging phase and that from charging to discharging phase both achieve zero overshoot
with the adjustment time reduced by 34.7% and 68.4%
respectively.
