Model set identification for H<inf>&#x221E;</inf> robust control of Hydraulic Flight Motion Simulator

Abstract

A model set identification approach is presented for H ∞ robust control design of Hydraulic Flight Motion Simulator servo system, which suffers from various uncertainties, such as parameter uncertainty, high frequency unmodelled dynamic uncertainty, and so on. The identification approach consists of two steps. To be exact, the first step is nominal model parameter identification, and then model uncertainty estimation. The nominal model parameter identification is based on the grey-box method. The model uncerta…
