Research on the Load Characteristics of the Ball Nozzle Based on the Control Strategy of Stiffness Adaptive Compensation

This paper first discusses the application prospect and advantage of the load characteristics of the ball nozzle distinguish from the flexible nozzle. On the influence of the no-linear characteristics to the thrust vector control (TVC), the key factor was searched from the category and identification method of the ball nozzle characteristics. Then one kind of control strategy of stiffness adaptive compensation was provided to solve the problem that the dynamic characteristic of the control system was not meted and proved it's valid after simulation.
