Flatness-based estimated state feedback control for a rotating flexible beam: experimental results

A novel flatness-based estimated state feedback control design for a rotating flexible beam is introduced. The horizontally rotating beam is modelled as a boundary controlled Euler-Bernoulli partial differential equation. A so-called flat output is introduced in order to parameterise the system´s variables in power series. These series lead to open- and closed-loop controls which can solve finite-time motion planning problems. The performance of the proposed control is experimentally compared with existing control methods for certain rest-to-rest motion planning problems.
