Abstract

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.
