摘要:
 针对PNC 型三电平逆变器单桥臂故障和母线电压分压不均衡等问题,研究了驱动系统在故障状态下的运行模式,提出了一种基于电流反馈特性的三相八开关容错逆变器( TPESFTI) 的驱动控制策略,并构建其拓扑结构和输出电压模型; 结合模型预测控制理论和扩张状态观测器( ESO)技术,提出了一种TPESFTI 的PMSM 驱动系统有限控制集模型预测控制( FCS-MPC) 策略。考虑系统参数变化对反电动势的影响,利用ESO 方法,实现了对反电动势进行实时性估计; 同时采用FCSMPC中目标函数的非线性约束项来降低逆变器的开关频率。仿真结果表明,该控制策略能够确保TPESFTI 的PMSM 驱动系统稳定可靠运行,并且能有效地抑制母线电容分压不均对系统的影响以及降低开关损耗,同时具有良好的动态性能、较强的抗负载能力和鲁棒性。
Abstract:
  The operation mode of driving system under fault conditions is studied aiming at the single bridge arm fault and unbalanced bus voltage dividing of PNC three-level inverter. A drive control strategy is proposed for three phases eight-switch fault-tolerant inverter ( TPESFTI) with current feedback characteristics,and its topology and output voltage model are constructed. Combing model predictive control theory with extended state observer ( ESO) technology,a finite control set model predictive control is proposed
for PMSM systems driven by three-phase eight-switch fault-tolerant inverter. Considering the influence of system parameter changes on the back EMF,an observer was designed by extended state observer ( ESO) technology to realize the real-time estimation of the back EMF. The nonlinear constraint term of the objective function in FCS-MPC was used to reduce the switching frequency of the inverter. The simulation results show that the control strategy can ensure the reliable and stable operation of TPESFTI drive
PMSM system,which effectively suppresses the adverse effect resulting from the unbalance of DC link capacitor voltages on the system and reduce switching loss,and has good dynamic performance,strong load resistance and robustness .
