Development and Application of Control System for High Angle of Attack Mechanism in 2.4m Wind tunnel

Aiming at the problems that the performance of the mechanism at high angle of attack in 2.4m transonic wind tunnel (hereinafter referred to as 2.4m wind tunnel) is degraded, and the stability and positioning accuracy of the mechanism can not meet the test requirements during operation, the motion control system of the mechanism is redeveloped, and a bidirectional control algorithm is designed, which effectively solves the problems of running jitter and poor positioning accuracy of the mechanism at high angle of attack. The system has been put into use in 2.4m wind tunnel at high angle of attack, and the results show that the application effect is well.
