A Design Approach for Feedforward Control of Transport Processes with Spatially Distributed Input

Considered are distributed parameter systems with dominant transport behaviour which are described by linear first order partial differential equations. It is assumed that the input acts spatially distributed and can only be varied in time. For such systems, an approach is proposed in order to design a model-based feedforward control whereby the input trajectory is parameterized by the output reference trajectory and by its first time derivative. In addition, a measured boundary disturbance can be compensated. The experimental application of feedforward control design is illustrated for a set-point change of an industrial glass feeder.
