This article proposes a novel model predictive control (MPC) scheme for dual three-phase permanent magnet synchronous machines (DTP-PMSMs) to further suppress the $x-y$ current harmonics caused by unmodeled disturbances such as inverter nonlinearity and back-EMF harmonics, in which the average deception effect is taken into account to avoid larger $x-y$ current spikes. Instead of following the conventional virtual vectors (VVs) to synthesize a zero-average voltage in the $x-y$ subspace, the rotating nonzero voltage vector is dynamically modulated in a control period by scheduling the dwell times of the three adjacent large vectors and zero vectors to realize the closed-loop current control in the $x-y$ subspace. In the implementation of synthetic vectors, to ensure that large vectors with a higher ratio of $\alpha -\beta / x-y$ voltage are applied directly to the inverter, the compared registers A and B of the PWM module are configured to solve the state conflicts issue in the switching sequence. Since the $x-y$ unmodeled disturbances have considerable periodic components, a resonant extended state observer (RESO) is employed to provide a more accurate estimate within a limited bandwidth, resulting in more targeted suppression of the fifth and seventh harmonics. Experimental results validate the superiority of the proposed strategy.

考虑平均欺骗效应的基于合成矢量的双三相 PMSM 电流谐波抑制预测控制


本文提出了一种双三相永磁同步电机 (DTP-PMSM) 的新型模型预测控制 (MPC) 方案，以进一步抑制由逆变器非线性和反电动势谐波等未建模干扰引起的 $x-y$ 电流谐波，其中考虑了平均欺骗效应以避免更大的 $x-y$ 电流尖峰。不是按照传统的虚拟矢量 (VV) 在 $x-y$ 子空间中合成零平均电压，而是通过调度三个相邻大矢量和零矢量的驻留时间，在控制周期内动态调制旋转非零电压矢量实现$x-y$子空间的闭环电流控制。在合成向量的实现中，为了确保具有较高比率$\alpha -\beta / x-y$电压的大向量直接施加到逆变器，配置了PWM模块的比较寄存器A和B来求解状态切换顺序中的冲突问题。由于 $x-y$ 未建模扰动具有相当大的周期性分量，因此采用谐振扩展状态观测器 (RESO) 在有限带宽内提供更准确的估计，从而更有针对性地抑制五次和七次谐波。实验结果验证了所提出策略的优越性。
