摘要

提出了三相两电平并网变流器的电压调节和电流跟踪控制策略。利用幂不变的Park变换，得到了dq同步参考系下功率变换器的平均数学模型。然后，提出了一种新的控制策略，利用自适应控制和${H}_{\infty }$技术来调节直流输出电压，并跟踪三相功率整流器所需的参考电流。更具体地说，在外环中建立了一个有效的自适应控制器，用于在存在外部干扰的情况下调节直流链路输出电压。在内部回路中设计了一组${H}_{\infty }$控制器，以强制输入电流跟踪其所需值。最后，对所提控制方法的仿真结果进行了分析，并与滑模控制进行了比较，验证了所提控制律的优越性。

Adaptive Control for Three-Phase Power Converters With Disturbance Rejection Performance

This paper presents voltage regulation and current tracking control strategies for three phase two-level grid-connected power converters. By using power-invariant Park’s transformation, an averaged mathematical model of power converters is obtained in dq synchronous reference frame. Then a novel control strategy using adaptive control and

${H}_{\infty }$

technique is proposed to regulate the dc-link output voltage as well as track a desired current reference for three-phase power rectifiers. More specifically, an efficient adaptive controller is established in the external loop for regulating dc-link output voltage in the presence of external disturbances. A set of

${H}_{\infty }$

controllers are designed in the internal loop to force the input currents track their desired values. Finally, simulation results obtained from the proposed control method are presented, analyzed, and compared with that of sliding mode control, and the superiority of the proposed control laws is verified.
