摘要

Hyper-gravity environment simulation is an important method of performance evaluation with high accelerations. Periodic cylindrical wind field is a major interference when the simulator operates at high speed. This introduces unexpected stress into the structure, causes vibration of the rotating part, and reduces comfort of the pilot. In this paper, dynamics of hyper-gravity simulators are described by a single-link flexible manipulator with tip mass. Distributed-parameter model of the manipulator is derived together with description of wind resistance. The result is a two-time scale description of the dynamics such that singular perturbation method can be adopted for control design. A composite control strategy is used whose objective is to track desired position while keeping structural oscillation at a lower level despite of wind disturbances. Sliding-mode control is applied in this preliminary study thanks its robustness against model uncertainties. Feasibility and effectiveness of the proposed modelling and control scheme are verified with simulative investigation.
