The sliding mode control and optimization are investigated for a class of nonlinear
neutral systems with the unmatched nonlinear term. In the framework of Lyapunov stability theory,
the existence conditions for the designed sliding surface and the stability bound are derived via
twice transformations. The further results are to develop an efficient sliding mode control law with
tuned parameters to attract the state trajectories onto the sliding surface in finite time and remain
there for all the subsequent time. Finally, some comparisons are made to show the advantages of our
