Luenberger Observer Based on Integral Predictive Current Control for Dual Three-Phase PMSM Drives
摘要
In this paper, a robust integral predictive current control (IPCC) for dual three-phase PMSM is proposed, which can compensate model uncertainty and control delay, and enhance system stability. The external disturbance and parameter mismatch can be eliminated by increment model. The integral action can reduce the steady-state error. Luenberger observer (LO) is used to overcome the effect of control delay. Simulation results show effictiveness of the proposed IPCC.
