Open-loop temperature control for a distributed parameter model of a pipe

摘要

Various models describing a plug flow through a pipe are used for model-based control design in industrial processes. This contribution presents a feedforward controller based on a new modeling approach for plug flow through a pipe. The latter model combines the advantages of partial differential and delay differential equation approaches. This structure allows to derive the desired control input by an inverse calculation of the partial differential equation part of the model. Moreover, the stability of the used model is proven by a spectrum analysis of the involved system operators. Finally, the presented approach is studied in simulation and experimentally test results are provided.
