The paper introduces into the concept of model-based force estimation of flexible structures with impacts. The advantage of using extended PI-Observer (MAPIO) in comparison with the well-known PI-Observer is investigated with respect to the reconstruction of a complex nonlinear unknown input. Therefore a clamped beam example is considered. The task of the observer scheme is to estimate the tip position and the effecting input as unknown input. This task is also realized in the presence of measurement noise. The reconstruction of complex nonlinear spring behavior is performed to prove the performance of MAPI-Observer in comparison to PI-Observer.
