Based on vehicle-to-grid technology, electric vehicles can be used as power sources in the case of power failure. With the aim to reduce voltage overshoot and improve the anti-disturbance ability of the vehicle-to-grid inverter, a high-performance voltage control strategy based on funnel control and finite-time disturbance observer is developed. First, the dynamic model of the inverter in dq-frame is established, and the lumped disturbance including the unmodeled part is considered. Next, a novel funnel variable is proposed to ensure that the voltage tracking error can be stabilized within the prescribed funnel boundary, and thus enhance the transient performance. Then, a novel finite-time disturbance observer is designed to estimate the lumped disturbance in the system such as load fluctuations, and improve the anti-disturbance ability of the controller. Moreover, the second-order sliding mode differentiator is introduced to estimate the derivative of the virtual control law and eliminate the explosion of complexity problem in the derivation process. Finally, the finite-time stability of the proposed voltage control strategy is analyzed via the Lyapunov theory. The effectiveness of the proposed control strategy is verified by two cases.

基于车辆到电网技术，在停电的情况下，电动汽车可以用作动力源。为了减少电压过冲并提高车对网逆变器的抗干扰能力，提出了一种基于漏斗控制和有限时扰动观测器的高性能电压控制策略。一，dq中逆变器的动力学模型建立框架，并考虑包括未建模部分在内的集总扰动。接下来，提出了一种新颖的漏斗变量，以确保电压跟踪误差可以稳定在规定的漏斗边界内，从而提高瞬态性能。然后，设计了一种新颖的有限时间扰动观测器，以估计系统中的集总扰动，例如负载波动，并提高控制器的抗扰能力。此外，引入了二阶滑模微分器，以估计虚拟控制律的导数，并消除了推导过程中复杂性问题的激增。最后，通过李雅普诺夫理论分析了所提出的电压控制策略的时限稳定性。
