| 摘要: |
| 针对电传飞控作动系统采用主-主工作模式而产生的力纷争问题，从系统安全性角度出发考虑成熟可靠的控制律，提出了惯性积分和PI控制力均衡算法。通过对2种算法的权衡研究，最终决定采用PI控制。同时对作动系统物理模型进行等效转换、动力学分析、位置闭环伺服控制数学建模及AMEsim建模仿真分析，结果表明采用PI控制可以使静态力纷争几乎减小为零，使动态力纷争降低到1.288 9×106 Pa，比设计指标低62.58%。仿真模型验证了设计的力纷争均衡算法的可行性，能够为后期地面台架力纷争均衡试验提供理论依据。 |

| Abstract: |
| Aiming at the actuation system force fight problem resulted from active-active operational mode of fly-by-wire aircraft, and considering the technical maturity and reliability from safety aspect, the inertial integration algorithm and PI control law are established. After tradeoff study on these two methods, the PI control law is selected lastly.By physical model equivalent transformation, mechanical kinetics analysis, position closed-loop servo control modeling and AMEsim modeling and simulation analysis of the actuation system, the results show that using PI control can make the static force fight almost decrease to zero, make the dynamic force fight decrease to 1.288 9×106 Pa, 62.58% lower than requirement.It demonstrates the feasibility of the designed PI control law, and can be taken as the theoretic evidence of the forthcoming force fight equalization test on test rig. |
