Modeling and Simulation Performance Analysis of Wind Tunnel Electric Putter Control System

In a hypersonic wind tunnel, the motion of the electric putter Y mechanism needs to be controlled synchronously, and the accuracy or control performance of the system's synchronous motion control directly affects the running quality of the wind tunnel. Based on the deviation coupling mechanism of output displacement, the paper puts forward the synchronous control system of the model mechanism electric putter Y mechanism, and establishes the dynamic model of the mechanical system, current control ring, speed control ring and position control ring of the electric putter Y mechanism. A closed-loop synchronous three-ring control system is designed, and performance simulation is carried out. The results show that the system has fast synchronous response speed, high accuracy of synchronous displacement and synchronous speed control, and the system has strong robustness.
