In this study, the problem of finite‐time feedback stabilisation for switched linear input‐delay systems with saturating actuators is addressed by virtue of the comparison‐function‐like method. Finite‐time state feedback stabilisation is discussed and controllers are designed to make the closed‐loop systems finite‐time stable. Moreover, for the case that the states are unmeasured, observers are constructed to estimate the unavailable states and the observer–controller compensator strategy is proposed. Based on the results proposed in this study, information of transient performance of the controlled switched systems can be obtained and bounds of system trajectory are estimated. An example is employed to illustrate the effectiveness of the proposed approach.
