In this paper, an adaptive backstepping terminal sliding mode control (ABTSMC) method based on a double hidden layer recurrent neural network (DHLRNN) is proposed for a DC-DC buck converter. The DHLRNN is utilized to approximate and compensate for the system uncertainty. On the basis of backstepping control, a terminal sliding mode control (TSMC) is introduced to ensure the finite-time convergence of the tracking error. The effectiveness of the composite control method is verified on a converter prototype in different test conditions. The experimental comparison results demonstrate the proposed control method has better steady-state performance and faster transient response.
本文针对DC-DC降压变换器，提出了一种基于双隐层递归神经网络（DHLRNN）的自适应反步终端滑模控制（ABTSMC）方法。利用DHLRNN对系统不确定性进行逼近和补偿。在反步控制的基础上，引入终端滑模控制（TSMC）以确保跟踪误差的有限时间收敛。在不同测试条件下的变换器原型上验证了复合控制方法的有效性。实验对比结果表明，所提出的控制方法具有更好的稳态性能和更快的瞬态响应。
