The invention discloses a fusion type adaptive robust-based electro-hydraulic load simulator force control method and belongs to the electro-hydraulic servo control field. The method specifically comprises the steps of establishing a mathematical model for an electro-hydraulic load simulator; determining an adaptive law for the parameters of the electro-hydraulic load simulator; and designing a fusion type adaptive robust-based controller for control the force of the electro-hydraulic load simulator. According to the invention, the defect in the prior art that the output of the indirect adaptive control is poor in tracking performance is overcome by adopting the fast and dynamic compensation method. Therefore, the tracking performance of the system is improved. At the same time, the parameter estimation and the robustness are completely separated in design, so that the parameter estimation is less likely to be influenced by the sampling operation or by the noise. In this way, the parameter estimation accuracy is improved.
