• A modified design process of finite-time control (FTC) is achieved by utilizing prescribed performance control (PPC) and pre-assigned finitetime function (PFTF).

• The states can converge to a predefined region within the pre-assigned finite-time.

• The proposed method is more flexible and simpler since the convergence time is not related with the design parameters and initial values.

• Nussubaum gain is employed to tackle the FTC problem for parameter systems with unknown signs.
