State feedback time-optimal controller for linear systems with input delay

Soft variable structure control in time-delay systems with saturating input

“…The transient time can be reduced by using nonlinear control, ideally, time-optimal performance can be achieved. Unfortunately, despite significant effort in the past [5] and recent achievements [3,18], a time-optimal control law is difficult to synthesize and implement. The time-optimal control system is also susceptible to uncertainty (even small numerical errors can render it unstable).…”
