对于工作在断续导通模式（DCM）的升压变换器，反馈和前馈补偿器被广泛用于提高变换器的性能。然而，同时优化负载瞬态响应（LoTR）、线路瞬态响应（LiTR）和参考跟踪速度（RTS）是相对困难的，因为这些优化需要不同且不兼容的补偿器。为了解决这个问题，本文提出了一种叠加补偿策略，它由一个反馈补偿器和两个前馈补偿器组成。每个补偿器根据一个目标传递函数进行调整，从而优化LoTR、LiTR和RTS。根据线性叠加原理，将输出相加作为占空比。通过设计前馈补偿器以适应反馈补偿器，提高了补偿器的兼容性。此外，基于闭环模型，给出了目标传递函数的设计规则，以最小化数字控制器固有的采样保持效应和计算延迟的影响。最后，变换器的LoTR、LiTR和RTS同时得到优化，闭环幅频图、状态轨迹分析和实验结果证明了这一点。
For boost converter operating in Discontinuous Conduction Mode (DCM), feedback and feedforward compensators are widely used to improve the converter performance. However, it is relatively difficult to optimize Load Transient Response (LoTR), Line Transient Response (LiTR) and Reference Tracking Speed (RTS) simultaneously, since the optimizations require different compensators that are incompatible. In order to solve the issue, a superposed compensation strategy is proposed in this paper, which consists of a feedback compensator and two feedforward compensators. Each.compensator is tuned according to an objective transfer function, which optimizes LoTR, LiTR and RTS. The outputs are summed as duty cycle according to linear superposition principle. Compatibility of the compensators is improved by designing the feedforward compensators to adapt to the feedback compensator. Furthermore, based on the closed-loop model, design rules for the objective transfer functions are given to minimize the influences of sample-and-hold effect and calculation delay, which are intrinsic in digital controller. Finally, converter LoTR, LiTR and RTS are simultaneously optimized, which is proved by closed-loop magnitude-frequency plots, state trajectory analyses and experimental results.
