The paper centers on the H finite-time (FT) composite anti-disturbance switching control (ADSC) issue for switched systems (SSs) suffered from multiple disturbances, the unavailable modeled disturbance and the available un-modeled disturbance. The aim is to arrive at the multiple disturbance suppression in FT. A switching estimator is firstly constructed to observe the modeled disturbance combined with the unavailable system state. A switching controller and a switching law are then co-established to restrain the multiple disturbances in the SSs. A condition is attained to ensure that the H FT composite ADSC issue for the SSs is solvable, even the issue is not solvable for subsystems. A verification example is served to text the reasonability of the developed theory.
本文围绕受多种干扰（包括不可测的建模干扰和可测的未建模干扰）影响的切换系统的H有限时间（FT）复合抗干扰切换控制（ADSC）问题展开。目的是实现有限时间内的多种干扰抑制。首先构造一个切换估计器，结合不可测的系统状态来观测建模干扰。然后共同设计一个切换控制器和一个切换律，以抑制切换系统中的多种干扰。得到了一个条件，以确保切换系统的H有限时间复合ADSC问题是可解的，即使子系统的该问题不可解。给出了一个验证例子来检验所提出理论的合理性。
