Abstract

A class of nonlinear systems with input dependent parameters and time delays has been considered, for which the output is oscillatory. As for δ-flat systems, the open-loop motion planning problem can be solved using an explicit parametrization of trajectories; however, it is shown that the structure of the system brings out some constraints on the input and therefore limits the possible choice of trajectories. An example is provided, in which the trajectory is piecewise polynomial, where the open loop control and the corresponding constraints are explicitly given
