Abstract

In this paper, an intelligent position control method based on independent load control is designed for digital electro-hydraulic actuator of rocket nozzle, which can achieve smooth position control of digital electro-hydraulic actuator. According to the requirements of rocket nozzle, the matching design of digital valve set is completed. Combining the independent load characteristics and energy efficiency characteristics of digital valve system, an intelligent research algorithm of position control is improved and put forward. In this paper, a complete digital electro-hydraulic actuator system model of rocket nozzle is established, and the control effect of position control algorithm is verified by simulation algorithm. The simulation results show that, compared with the input amplitude of 100mm, the following error of the system is 0.3mm, which achieves higher control precision and has better rapidity and high-frequency response characteristics.
