基于遗传算法的平均电流控制电路的优化设计
资料介绍
平均电流控制是较常见的一种控制方法，它可以工作于CCM和DCM工作方式下，可以在输入电压、负载变化范围比较大的场合得到质量很高的电流波形。本文对平均电流控制电路的电流环和电压环的控制参数进行了选择设计，并用改进后的遗传算法对其进行进一步优化设计。最后通过仿真实验证明，优化后，电流环和电压环的相位裕量及稳定性优于优化设计前。
Average current control is one of the more common control methods ; it can work in CCM and DCM mode and get the high qualified current waveform in the occasion that the input voltage and load range is larger. In this paper, the current loop and volt- age loop control parameters of average current control circuit is selected for designing, and the further optimization design is made with the using of improved genetic algorithm. Finally, the simulation experiments show that the phase margin and stability of the optimized current loop and voltage loop is superior to the design before.
