提出了一种结合线性插值法的抗绕组无功转移(AWBT)控制结构，用于平滑切换控制。通过选择合适的调度信号，不同的控制器可以在统一的框架下平滑切换。同时，通过控制器切换，可以保持闭环系统的H_2/H_∞性能、极点配置约束和无源性等鲁棒指标。此外，对于输入饱和的线性系统，可以保证闭环系统的稳定性和L2增益。最后，对小车-弹簧摆系统进行了仿真，验证了所提方案的有效性。
In this paper, an anti‐windup bumpless transfer (AWBT) control structure combined with linear interpolation method is proposed for smooth switching control. By choosing an appropriate scheduling signal, different controllers can be switched smoothly under a unified framework. Meanwhile, some robust specifications including H2/H∞ performance, pole placement constraint, and passivity of the closed‐loop system can be preserved through controller switching. Furthermore, for the linear system subject to input saturation, the stability and L2 gain of the closed‐loop system can be guaranteed. Finally, a cart‐spring pendulum system is simulated to demonstrate the effectiveness of the proposed scheme.
