Improved H8 Inverter-based Fast Three-vector Model Predictive Control
针对两电平三相逆变器永磁同步电机控制系统,提出一种基于改进型H8逆变器的快速三矢量模型预测控制策略.通过滚动优化从6个有效电压矢量中选出第一最优矢量;根据预测电流与参考电流的误差矢量角度,从相邻且误差最小的2个有效矢量中确定第二最优矢量.在电压矢量占空比计算方法上,通过集中规划矢量切换顺序避免等效零矢量的不利影响.仿真结果表明,文中方法在有效抑制CMV峰值、减少电流波动和降低谐波失真方面展现出较好的控制性能.
A fast three-vector model predictive control strategy based on an improved H8 inverter was proposed for permanent magnet synchronous motor control systems driven by a two-level three-phase inverter.The first optimal voltage vector was selected from six effective voltage vectors through rolling optimization.The second optimal vector was determined from two adjacent effective vectors with the minimum error according to the angle of the error vector between the predicted current and the refer-ence current.In the duty ratio calculation of voltage vectors,the vector switching sequence was planned centrally to avoid the adverse effect of equivalent zero vectors.Simulation results show that the pro-posed method presents better control performance in effectively suppressing the CMV peak,reducing current ripple,and decreasing harmonic distortion.
