Abstract

A model set identification approach is presented for H8 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 uncertainty estimation is implemented with model error modeling. Both nominal model and uncertainty bound are indispensable to H8 robust control design. Compared to the usual modeling method with math derivation and simulation, the proposed identification approach provides more accurate nominal model and uncertainty bound, and is more suitable for H8 robust control design of Hydraulic Flight Motion Simulator servo system. The identification procedure is illustrated with the Hydraulic Flight Motion Simulator inner gimbal servo system.
