This paper focuses on a robust control method applied to an electro-Hydraulic Load Simulator (HLS) acting on a special aerodynamic load. Owing to the high-speed on-off valve, some pneumatic aircraft actuators have inherent high-frequency motion disturbance that reduces the dynamic tracking performance. Through combining velocity synchronising decoupling compensation and equivalent disturbance observers, this paper presents a Dynamic Robust Compensation (DRC) to achieve high precision load simulation. The experiments indicate that the velocity synchronising decoupling is used to restrain strong disturbance, whereas the robust compensator is adopted to reduce the remaining extraneous torque from motion flutter efficiently further.
