Abstract

In this paper a semi-physical simulation platform has been designed for modeling and control of flexible multibody systems. On the platform experimental modeling with subspace identification method is performed. After a brief introduction to the platform design, the multisine exciting signal filtered by a reshaping filter is presented to improve the SNR of output data. Based on the identified mathematical model, two H_infin control schemes are designed and tested on the platform. Modeling and control experiments on the simulation platform validates the modeling and control schemes, and verifies the feasibility of the simulation platform.
