Abstract
The time-optimal trajectories are very sensitive to disturbances. The use of optimal strategy in real-time inevitably results in a departure from the optimal path. A return to the trajectory is no longer possible. When the time-optimal is replaced to the fix horizon problem then the real system moves from the optimal to nearing trajectories. Moreover, a further desensitization is possible by a proper shifting. The nearing desensitized trajectories are robust to disturbances at the cost of a slight increase in the control time.
