对于现代带电传操纵系统飞机,其人-机闭环系统是非线性高阶复杂系统。针对带电传操纵系统人-机闭环系统稳定性问题,运用遗传算法在频域内对人-机闭环高阶系统进行了等效拟配,提出应用根轨迹法对拟配得到的低阶等效系统进行稳定性分析。仿真结果表明,用遗传算法进行等效拟配能够避免初值选择问题,拟配精度较高。所提方法能够考虑到驾驶员环节,并且能与驾驶员关心的模态结合起来,从而验证了该方法的可行性和有效性。
For the modern flight control system aircraft, its man-machine closed-loop system is a nonlinear high-end complex system. Aiming at the stability problem of the man-machine closed-loop system with fly-by-wire manipulator, the genetic algorithm is used to fit the high-order closed-loop system of human-machine in the frequency domain. The proposed root locus method is applied to the low-order equivalent system Stability analysis. Simulation results show that the genetic algorithm to be equivalent to be able to avoid the choice of initial value selection problem, with high precision. The proposed method can take into account the driver link, and can be combined with the driver’s concern mode, which verifies the feasibility and effectiveness of the method.
