This article provides a nonsingular predefined-time terminal sliding mode control scheme for perturbed chains of integrators. Based on the linear delayed feedback technique, a class of nonsingular smooth prescribed-time sliding surfaces with artificial time-delays is constructed, and the control scheme can achieve predefined-time control for perturbed chains of integrators with matched and mismatched disturbances. Especially, for double integrators, an initial-condition-based sufficient condition is provided to preserve the prescribed-time stability. Finally, several simulation results illustrate the performance of the proposed control scheme.
