| 摘要: |
| 首先建立了主动控制起落架系统的非线性动力学模型。然后根据最优控制理论,在Matlab的环境下,应用人工鱼群算法设计了多目标最优的PID控制器。最后应用Simulink控制系统仿真软件对主、被动起落架在地面信号为弹伤跑道信号的条件下进行了性能仿真。对仿真结果进行了分析比较,得出的结论是利用最优控制理论设计的多目标最优的PID控制器的主动控制起落架能显著降低飞机的振动冲击载荷,提高飞机机体和起落架的疲劳寿命,降低跑道不平度对飞机机体和起落架的冲击载荷和振动响应;同时提高飞机的滑行品质和乘客的舒适性。 |

| Abstract: |
| First of all, the nonlinear mechanical model of the active-control landing gear system is developed. Then, the PID controller of optimization is designed according to the optimal control theory in the environment of Matlab with Artificial Fish-Swarm Algorithm.Last, the performance of active and passive control landing gears are simulated under the condition that signal of runway is the signal of the repaired airplane runway after being bombed in the environment of Simulink.Through the analysis and comparison of the simulation results, the conclusion is that, the optimal PID controller, which is designed on the basis of the optimal control theory, can reduce the shock load dramatically, prolong the fatigue life of the fuselage and landing gear system, and improve the taxiing perform-ance and ride comfort simultaneously. |
