摘要:

摘要：推力矢量试验装置是进行战斗机过失速机动和直接力控制模式超机动能力试验的装置。结合推力矢量试验装置的特性，推力矢量试验需要对多路高压、大流量气流进行精确的流量控制。通过推力矢量试验装置的特性分析，提出多模型控制的策略。针对不同阶段的特点和控制任务要求，分别采用基于专家系统、智能PID以及补偿解耦等控制策略，实现高压、大流量条件下的高精度流量控制。从调试运行结果看，流量控制精度达到3～5‰的水平，满足了推力矢量试验的对流量精准度的要求。

Abstract:

Thrust vector test equipment is a device for super maneuverability test of fighter after stall maneuver and direct force control mode. Thrust vector test requires accurate flow control of multi-channel high-pressure and large-flow airflow. Based on the analysis of the characteristics of the thrust vector test device, the multi-model control strategy is put forward. According to the characteristics of different stages and the requirements of control tasks, control strategies based on expert system, intelligent PID and compensation decoupling are adopted to achieve high-precision flow control under high pressure and large flow conditions. From the results of debugging and operation, the accuracy of flow control reaches 3-5‰, which meets the requirement of flow accuracy in thrust vector test.
