Abstract
The flatness-based feedforward tracking control design based on formal power series is extended to distributed parametersystems (DPS) with input constraints. Thereby, formal power series and suitable summation methods are utilized to derive a finite-dimensional approximation in generalized controller form coordinates. This representation serves as the basis for a novel feedforward control design approach, which treats the considered finite-time transition between equilibrium profiles as a two-point boundary value problem (BVP) with input constraints. Simulation results for a linear heat conduction system and anonlinear diffusion-convection-reaction system (DCRS) illustrate the applicability of the approach.
