The vehicle safety seat supports an occupant and includes structure interconnecting the seat and the vehicle. The interconnecting structure is adapted to constrain the seat, upon vehicle deceleration, to follow a trajectory with respect to the vehicle which substantially minimizes a cost function associated with occupant injury. In a preferred embodiment, the structure constrains the mass center and seat angle to follow trajectories which substantially minimize primarily forward motion of the occupant in the vehicle frame of reference.

A sequence of impulses is determined which eliminates unwanted dynamics of a dynamic system. This impulse sequence is convolved with an arbitrary command input to drive the dynamic system to an output with a minimum of unwanted dynamics. The input sequence is time optimal in that it constitutes the shortest possible command input that results in no unwanted dynamics of the system subject to robustness and implementation constraints. The preshaping technique is robust under system parameter uncertainty and may be applied to both open and closed loop sy
