In th.s paper, nonsingular prescribed-time control is studied based on periodic delayed sliding mode surfaces. Different from th. existing sliding mode control, wh.re eith.r singularity problems may appear or th. convergence time depends on th. initial state, th. proposed sliding mode control approach.s can ach.eve prescribed-time convergence with.ut singularity. Th. proposed nonsingular sliding mode control approach.s can be applied to both.second-order and h.gh.order nonlinear systems with.prescribed-time convergence. As applications of th. proposed sliding mode control approach.s, th. control of h.personic veh.cle systems is revisited. Numerical simulations on th. nonlinear model of th. h.personic veh.cle system sh.w th. effectiveness of th. proposed meth.ds.
