Research on dynamic robust compensation decoupling controller of hydraulic flight simulator

Using dynamic robust compensation for decoupling is proposed for the serious nonlinear coupling of hydraulic flight simulator. By this method decoupling can be realized without requesting the decoupling network. At the same time it can be realized online easily and occupy very few computer resources. A new way is opened for simulator decoupling control. The simulate experiment results show the effectiveness of the proposed decoupling controller. And the nonlinear coupling of simulator system is resolved. On the other hand, the simulation results show that the hydraulic system with the proposed method can satisfy performance robustness, and guarantee a better performance for restraint disturbance and tracking of input signal for parameter uncertainty.
