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 *** 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 *** 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 *** proposed modified LADRC strategy improved both the steady-state performance and dynamic response of the DTP-PMSG *** experimental results demonstrate that the proposed strategy is both feasible and effective.

Active disturbance rejection control（ADRC） is now widely applied in motor drives due to its advantages like independence of system models and better disturbance rejection ability. For the current loop of PMSM, the uncertainties like model coupling and parameter variation can be estimated and compensated by ADRC. Considering that the total disturbance of current loop can be partially compensated for by available plant characteristics, the idea of model compensation can be applied to ADRC controller. However, the filter link in current feedback loop is usually ignored in conventional model compensation approach. Therefore, a modified model-compensation ADRC current control strategy considering the filter link effect is proposed in this paper, with simulation results show that better current tracking performance is achieved by the proposed control strategy.

In this paper,high order observer（HOO） and integral sliding mode controller（ISMC） are studied in the system of permanent magnet synchronous motor（PMSM） with the uncertainty *** system is divided into two loops:current loop and speed loop for ISMC and *** can get the estimated value of external interference and the uncertain parameters’ *** estimated value got from HOO will also be accurate because of the high-order characteristic of *** with the estimated disturbance has better robust and *** simulations prove the effectiveness of the ISMC and HOO.
