In order to improve transient response and robust tracking performance, an adaptive nonsingular terminal sliding mode control (ANTSMC) strategy is developed for bidirectional dc–dc converter (BDC) of hybrid energy storage systems (HESSs). By using the adaptive rules, the estimated values of load variations, external input voltage, input current, and output voltage can be obtained. Then, the voltage tracking error can be calculated based on the estimated value and the actual value. The fast terminal SMC strategy is proposed such that the tracking error converges in a finite time. Simulation results, compared with conventional PID, second-order sliding mode, show that output voltage can robustly track the reference voltage with fast response.

混合储能系统双向 DC-DC 转换器的自适应非奇异终端滑模控制
为了提高瞬态响应和稳健的跟踪性能,为混合储能系统 (HESS) 的双向 DC-DC 转换器 (BDC) 开发了一种自适应非奇异终端滑模控制 (ANTSMC) 策略。通过使用自适应规则,可以获得负载变化、外部输入电压、输入电流和输出电压的估计值。然后,可以根据估计值和实际值计算电压跟踪误差。提出了快速终端 SMC 策略,使得跟踪误差在有限时间内收敛。仿真结果与传统的 PID、二阶滑模相比,表明输出电压可以稳健地跟踪参考电压,响应速度快。
