中文摘要:作为航空飞行器的动力装置,冲压发动机以其高推比性能日益应用广泛,其控制系统的好坏直接影响着其工作性能。推力控制系统是冲压发动机控制系统的重要组成部分,良好的推力控制器使其在复杂环境和比较宽的马赫数下获得很好的鲁棒性。本文利用MATALB仿真软件的Simulink工具箱建立推力控制系统的仿真模型,采用模糊PID控制方法对冲压发动机推力回路进行控制,通过调节参数,设计出高性能的控制器。其后对设计出的模糊PID控制器进行动稳态性能、鲁棒性、抗干扰性以及跟踪性的测试,并将其控制结果与设计的传统PI控制以及鲁棒控制的结果进行对比分析。仿真结果表明,设计的模糊PID控制器在动稳态性能、鲁棒性、抗干扰性以及跟踪性能方面,都可以达到很好的性能。

Fuzzy PID Research of Ramjet Thrust Control System
Abstract:As the power plant of spacecraft ramjet has been widely used with the high push performance, the working performance has been influenced by the control system directly. Thrust control system is an important constituent of the ramjet control system, and a good robustness can be obtained in the complex environment and in the broad mach number through a super thrust controller. The simulation model of the thrust control system is established with the help of Simulink tool box of MATALB software, a high performance can be obtained in thrush control by using the Fuzzy PID control strategy and by adjusting the control parameters. Then comparisons have been made with the dynamic state property, steady state property, robustness, anti-jamming and tracking property, among the strategies of fuzzy PID control, traditional PI control and robust control. The simulation results and the analysis show that the fuzzy PID control strategy can achieve better performance in dynamic state performance, steady state performance, robustness, anti-jamming and tracking performance.
