| 摘要: |
| 利用状态空间平均法建立了双向DC-DC变换器的平均状态空间模型.在该模型基础上提出一种新颖的基于变量代换和参数估计的复合校正电流内环、电压外环双闭环控制策略.所采用变量代换的方法实现电流、电压双闭环内部的解耦.电流、电压环调节器均采用串联校正环节加PI调节器来将系统模型整定为标准二阶系统,并得到了控制参数计算公式,分析了电压外环的抗扰特性,为具体的控制参数的选择提供一定依据.对所采用的上述控制策略进行了仿真和实验研究.该控制策略控制简单,易于工程实现,仿真结果表明采用该控制策略为三重化双向DC-DC变换器所设计的调节器参数能满足各项动、稳态性能指标,工况间切换良好,且对负载大范围扰动、输入电压突变及电感值变化均具有良好的鲁棒性. |

| Abstract: |
| The average state variable model is developed using the average state variable method,based on which a dual close-loop control strategy is proposed with compound regulation. The inner current loop and outer voltage are decoupled using the variable replacement and set as the standard second-order system applying the serial corrector and PI regulator. For the control parameter selection,its calculation formula is derived and the anti-disturbance performance of the outer voltage loop is analyzed. The proposed ... |
