Abstract [en]

A block-oriented approximate feedback linearization for control of a pneumatic cylinder positioning system is introduced and a rather detailed discussion is presented on the uncertain linearization residual characterization. It is shown that making use of the characterized gain-phase information of the linearized system leads to a more reasonable trade-off between performance and stability in the QFT control design and thus results in high control performance. Simulation and experimental results are shown.
