Summary This article addresses the finite‐time (FT) input bumpless transfer (BT) control problem for switched systems. First, the performance of the input BT is described, quantifying the energy difference caused by the input signal jumps. The objective is to suppress large jumps during switching. Second, a sufficient evidence is established through the multiple Lyapunov functions method to ensure that the switched systems satisfy both the FT property and input BT performance. Also, this evidence allows that the control issue may not be addressed by subsystems. Then, a switching controller and a switching rule are simultaneously constructed for purpose of addressing the issue of the FT input BT control for switched systems. Finally, an effective validation of the established control method is verified by an ‐18 aircraft model simulation.
