Abstract

For path planning and trajectory tracking it is necessary to find an input signal for a given output signal, i.e., it is useful to invert the plants model (system inversion). Up to now, system inversion was practical only for simple systems due to the amount of symbolical computations involved. The inversion of flat state-space systems using automatic differentiation will be discussed.
