基于很好的理由，将非线性控制应用于双有源桥（DAB）DC-DC变换器具有重要的意义。提出了一种基于滑模控制的直接功率控制器，用于DAB变换器的功率流控制。该方案充分利用了滑模控制和直接功率控制的优点，具有精确的参考跟踪、快速的动态响应、大信号稳定性以及对线路和负载扰动的鲁棒性。给出了该控制器的设计过程。仿真和实验结果验证了性能。与现有的控制方案相比，所提出的控制器具有更好的性能。线路和负载调整率分别为标称输出电压的0.25%和0.4%。
For very good reasons, there are significant interests in applying nonlinear control to dual-active-bridge (DAB) DC-DC converters. This paper presents a sliding-mode-based direct power controller for the power flow control of DAB converters. The proposed scheme exploits both the advantages of sliding-mode control and direct power control, thus leading to accurate reference tracking, fast dynamic response, large-signal stability, and high robustness against line and load disturbance. The design procedure of this controller is provided. Both simulation and experimental results are provided to verify the performances. Compared to the existing control schemes, the proposed controller exhibits better performance. The line and load regulation are 0.25% and 0.4% of the nominal output voltage, respectively.
