由功率电传作动器EHA(Electro-Hydrostatic Actuator)与EMA(Electro-Mechanical Actuator)构成的非相似余度作动系统取消了中央液压源和遍布机身的液压管路,同时克服了共性故障,是飞机多电化的发展趋势.阐述了非相似余度作动系统的结构组成与工作原理,考虑舵面空气负载和连接刚度,建立了在主动/主动工作模式下闭环系统数学模型.在此基础上,论述了非相似余度作动系统静态力纷争的产生机理,提出了采用调整电气参数偏差的方法补偿静态力纷争的思想,基于上述原理提出了3种减小静态力纷争的力均衡控制策略,并对其进行理论和仿真分析.最后,对3种力均衡控制策略在静态力纷争消除性、隔离性等方面进行了综合对比分析.分析结果对非相似余度作动系统的设计及力纷争的解决提供了理论依据. The non-similar redundancy system consisting of Electro-Hydrostatic Actuator (EHA) and EMA (Electro-Mechanical Actuator) cancels the central hydraulic source and the hydraulic pipeline all over the fuselage and overcomes the common faults , Is the development trend of multi-electrification of aircraft.The structure and operating principle of non-similar redundancy actuator system are expounded, and the mathematical model of closed-loop system in active / active working mode is established considering air load and connection stiffness of rudder surface. On the basis of this, the mechanism of the static force dispute in the system of non-similar redundancy is discussed, and the idea of ​​compensating the static force dispute by adjusting the deviation of electrical parameters is put forward. Based on the above principle, three kinds of force equilibrium Control strategy and its theoretical and simulation analysis.Finally, the three kinds of force equilibrium control strategy in the static force dispute elimination, isolation and other aspects of a comprehensive comparative analysis of the results of the non-similar redundancy design of the motion system And provide a theoretical basis for the solution of the dispute of power.
