摘　　要：为避免切换系统在切换瞬间出现控制信号颠簸,保证控制信号的连续性,提出了一种基于无扰滤波器和可容许边依赖平均驻留时间(AED-ADT)的无扰切换控制方法。首先,描述控制信号在切换时刻的颠簸,使用扩展AED-ADT方法对切换信号进行约束。其次,基于扩展AED-ADT方法设计无扰滤波器,并利用多Lyapunov函数稳定性分析方法对所设计控制器进行稳定分析,给出系统有限逗留时间和无限逗留时间指数稳定充要条件。最后,通过两个不同的AED-ADT参数仿真实验验证所设计算法的有效性。This paper studies the control problem of bumpless transfer based on bumpless transfer filters and admissible edge-dependency average dwell time method.In order to avoid the jerk of the control signal at the switching moment,a bumpless transfer control method is proposed,which ensures the continuity of the control signal and also satisfies the exponential stability of the closed-loop system.By using the bumpless transfer filter and AED-ADT method,the conditions for exponential stability of linear switching systems under bumpless transfer control(BTC)are given,and by some matrix inequalities,the system satisfies the bumpless transfer transmission control conditions.Finally,through two different AED-ADT parameter simulation experiments,the optimal controller parameters are obtained by solving inequalities,and the effectiveness of the algorithm is demonstrated by simulating control input-output.
