中文摘要:

针对Buck-Boost矩阵变换器（BBMC）逆变级在脉冲输入电压作用下存在的分叉与混沌现象，提出采用分段延迟反馈控制法，研究确定了其控制参数的稳定域。建立了该逆变级的离散迭代数学模型，针对该逆变级在分段延迟反馈控制法下的控制特性进行了分析，研究确定了实现系统稳定运行时控制参数k1、k2间的函数关系并确定了其稳定域范围，最后对上述理论分析的正确性进行了仿真验证。结果表明：分段延迟反馈控制能有效抑制BBMC逆变级在脉冲输入电压作用下所产生的混沌现象，对于确保BBMC逆变级的稳定运行具有重要意义。

英文摘要:

Aiming at the bifurcation and chaos of Buck-Boost matrix converter (BBMC) inverter stage under the action of pulse input voltage, a piecewise delay feedback control method is proposed to study the stability domain of its control parameters. The discrete iterative mathematical model of the inverter stage is established. The control characteristics of the inverter stage under the piecewise delay feedback control method are analyzed. The function relationship between the control parameters k1 and k2 during the stable operation of the system is determined. The stability domain range is determined. Finally, the correctness of the above theoretical analysis is verified by simulation. The results show that the piecewise delay feedback control can effectively suppress the chaotic phenomenon generated by the BBMC inverter stage under the pulse input voltage, which is of great significance for ensuring the stable operation of the BBMC inverter stage.
