Research on Speed and Position Precise Control about Actuating Hydro-Cylinder of Model Support Mechanism in Wind Tunnel

Abstract:

Electro-hydraulic servo system of stick support mechanism was set up, which was used to simulate the attack angle mechanism in wind tunnel. The compound control strategy with speed feed-forward and position feedback was presented. The speed feed-forward model was deduced. And the reasonable speed and position signals were designed, by which the undisturbed switching of the speed feed-forward control and the position feedback control was realized. The hydromechatronic model of electro-hydraulic servo system of stick support mechanism was established by co-simulation technology with AMESim and Motion. The simulation and experiment results conform to theoretical analysis and show that the position and speed of the cylinder can be controlled simultaneously with the technology of speed and position hybrid control.
