一种基于模糊控制的推力变向机构控制仿真

为了适应越来越恶劣的飞机作战环境,在原有的轴对称矢量喷管的数学模型的基础上,提出一种基于模糊控制的推力变向机构的构想.建立AVEN的数学模型,并进行模糊控制设计,通过Matlab的仿真说明该控制器可以有效地追踪输入信号的变化,同时进一步分析比较量化因子Ke、Kde和比例因子Ku对控制结果的影响,在此基础上设计模糊PID控制器,与单纯的PID控制器和模糊控制器进行比较.分析结果表明:该模糊控制器能够较为理想地跟踪输入,较为准确地分析各量化因子对输出结果的影响,为推力变向机构的工程实践提供理论参考.

Simulation of Thrust Control System Based on Fuzzy Control

For adapting worse and worse airplane fight environment, put forward a concept about thrust controlmechanism based on the fuzzy control according to the mathematical model of the original axis symmetric vectoringexhaust nozzle. Establish AVEN math model and carry out fuzzy control design. The Matlab simulation proves that thiscontroller can effectively track the input signal changes, and carry out further analysis and comparison of the quantizationfactors Ke, Kde and the proportional factor Ku effect on control results. On the basis of this, the fuzzy PID controller isdesigned and compared with the simple PID controller and fuzzy controller. The analysis results show that the fuzzycontroller can effectively track and input, and it can correctly analyze influence of quantization factors on output results,which provides a theoretical reference for the engineering practice of the thrust mechanism.
