The development of semi - active control technology and the equipment : magnetorhelogical fluids damps based in this technology were introduced . the discussion presented in this paper is this equipment applied on the aircraft landing gear 本文分析了半主动控制技术的发展概况并构建了磁流变阻尼器,并对其在飞机起落架上的应用作了进行了初步探讨。
This paper mainly researches the application of the active control technology to the landing gear system . the aim is using different control methods to design the active controller to improve the performance of the system , according to the characteristic of the parameters " variations 本文主要研究了主动控制技术在起落架缓冲器控制系统中的应用,针对缓冲器系统变参数的特点,运用不同的方法来对主动控制器进行了设计,达到了改善系统性能的目的。
Because of these characteristics , the variable stiffness sma bearing used in rotor system can be designed , and then the stiffness of system can be varied by active control technology when the rotate speed of system is near the critical rotate speed to reduce the maximum vibration amplitude of rotor system 利用这些特性可以设计出用于转子系统的可变刚度支承,通过结合主动控制技术,在临界转速附近改变系统刚度,从而降低系统在临界转速时的最大振幅。本文研究利用形状记忆合金对转子系统振动进行主动控制。
Direct side force control ( dsfc ) comes into being with the appearance of act ( active control technology ) . through maneuvering the vertical canard to produce side force , people can control a aircraft easily . so the trajectory of a vehicle can be controlled precisely , and it ' s maneuverability is greatly improved 直接侧力控制是随着主动控制的提出而出现的,采用直接侧力控制,可在不改变飞机姿态的条件下,直接通过控制面造成侧力来操纵飞机机动,从而达到精确控制飞行轨迹和增强机动能力的目的。
