为了提高一类电机泵阀并联式飞机机载作动系统的鲁棒性,设计了一种模糊变结构控制方法。该方法综合了模糊控制理论与变结构控制两者的优点,既具有模糊控制不依赖于对象模型的特点,又具有变结构控制鲁棒性强的特点,并通过选用不同形式的模糊控制方法来提高飞机机载作动系统适应复杂环境的能力。仿真结果证明了该文设计的模糊变结构控制系统能提高该类电机泵阀并联式机载作动系统的负载鲁棒性,且这种设计方法具有一定的工程可行性。同时也表明了这种模糊变结构控制方法对于飞机机载作动系统的设计具有理论与实践上的指导意义。
In order to improve the robustness of a kind of motor-pump parallel plane on-board maneuvering system, a fuzzy variable structure control method is designed. The method combines the advantages of both fuzzy control theory and variable structure control, which not only has the characteristics of fuzzy control not dependent on the object model, but also has the strong robust of variable structure control. By adopting different forms of fuzzy control methods Improve the ability of aircraft airborne motion system to adapt to complex environment. The simulation results show that the fuzzy variable structure control system designed in this paper can improve the load robustness of the parallel mounted onboard operating system for this kind of motor pump valve. This design method has certain engineering feasibility. At the same time, it also shows that this fuzzy variable structure control method has theoretical and practical significance for the design of aircraft on-board actuation system.
