摘要：
To resolve the problem about synchronous coordinated control of angle adjusting mechanism with multi-axis motion in wind tunnel, a synchronous control method including parallel control and cross-coupling control is proposed. Firstly, the parallel control method is applied to the multi-axis motion control. Based on the corresponding principle of the motion time and velocity alteration time between the front sideslip axis and the back sideslip axis, the improvement of the multi-axis synchronous performance is studied. Secondly, the cross-coupling control method based on synchronous error transfer function is taken, and the given motion parameters of the parallel control method can be corrected. Finally, the experiment is carried out on the angle adjusting mechanism. The results show that the proposed control method can reduce the horizontal synchronous error, the synchronous performance can be improved obviously, and the control requirement of test in wind tunnel can be fulfilled. The method has reference value to synchronous control of similar mechanism. © 2020, Editorial Department of Control Theory & Applications South China University of Technology. All right reserved.
