The objective of this paper is to design a finite-time
controller for Lorenz system in discrete-time. First, a discrete
model is derived through the Taylor series expansion. In the
next step, a discrete-time terminal sliding mode controller
(DTSMC) is developed to reach a finite-time and high precision
control. The stability analysis of DTSMC is presented in the
presence of external disturbance and model uncertainties.
Numerical simulations of Lorenz system are shown and
compared with a discrete-time sliding mode control (DSMC) to
illustrate the effectiveness of the proposed control scheme.
