Abstract: 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 the d-q subspace and harmonic currents in the x-y subspace. In the d-q subspace, the proposed strategy uses a model-based LADRC to enhance the decoupling effect between the d and q axes and the disturbance rejection ability against parameter variation. In the x-y subspace, the 5th and 7th harmonic current suppression abilities are improved by using quasi-resonant units parallel to the extended state observer of the traditional LADRC. The proposed modified LADRC strategy improved both the steady-state performance and dynamic response of the DTP-PMSG system. The experimental results demonstrate that the proposed strategy is both feasible and effective.
