Current loop disturbance suppression for dual three phase permanent magnet synchronous generators based on modified linear active disturbance rejection control

A modified four-dimensional linear active disturbance rejection control (LADRC) strategy is proposed for a dual three-phase permanent magnet synchronous generator (DTP-PMSG) system to reduce cross-coupling between the d and q axis currents in d-q subspace harmonic x-y subspace. In subspace, uses model-based LADRC enhance decoupling effect axes ability against parameter variation. 5th 7th current suppression abilities are improved by using quasi-resonant units parallel extended state observer of traditional LADRC. The both steady-state performance dynamic response DTP-PMSG system. experimental results demonstrate that feasible effective.
