提出了一种直接矩阵变换器（DMC）的组合控制策略，在不增加无源阻尼的情况下稳定输入侧滤波器，同时在输出端实现感应电机（IM）的磁场定向控制。具有辅助转矩控制的FOC的速度控制保持不变。转子磁链控制回路被扩展为级联结构，该级联结构另外服务于稳定输入滤波器的需要，特别是有功电网电流。无功电网电流由独立的控制回路控制，控制回路取决于FOC产生的输出侧条件。使用线性控制器，其要求基于瞬时功率的控制回路的线性化。实验结果证明了该方法的有效性。
This paper proposes a combined control strategy for direct matrix converters (DMC) to stabilize the input side filter without any passive damping, simultaneously realizing the field oriented control (FOC) of an induction machine (IM) at the output. The speed control of the FOC with subsidiary torque control is left untouched. The rotor flux control loop is extended to a cascaded structure that additionally serves the needs for stabilization of the input filter, especially the active grid current. The reactive grid current is controlled by separate control loops that depend on the output side conditions created by the FOC. Linear controllers are used, which demand linearization of the instantaneous power based control loops. The functionality is proven by experimental results.
