When planning trajectories, a reasonable demand on the generated curves is
that they interpolate through given points, or given intervals, at given sp
ecified times, or that they go through these points or intervals at times l
ying in specified time windows. This problem is addressed here as an optima
l control problem, minimizing the infinity norm of the inputs of a discreti
zed linear control system since the infinity norm minimization problem aris
es naturally when doing trajectory planning for both controlled switching s
ystems and non-holonomic robotic systems.
