基于分数阶滑模速度观测器的三电平逆变器驱动PMSM的模型预测电流控制
Model predictive current control for PMSM driven by three-level inverter based on fractional sliding mode speed observer
摘要
Abstract
Based on the fractional order theory and sliding mode control theory,a model prediction current control (MPCC) strategy based on fractional observer is proposed for the permanent magnet synchronous motor (PMSM)driven by three-level inverter.Compared with the traditional sliding mode speed observer,the observer is very simple and eases to implement. Moreover,the observer reduces the ripple of the motor speed in high frequency range in an efficient way.To reduce the stator current ripple and improve the control performance of the torque and speed,the MPCC strategy is put forward,which can make PMSM MPCC system have better control performance,stronger robustness and good dynamic performance.The simulation results validate the feasibility and effectiveness of the proposed scheme.关键词
