民用客机在垂直向紊流干扰下,会产生不期望的过载,导致乘坐品质下降。针对这一问题,提出了一种基于IM-PSO优化的载荷减缓控制设计方案。设计了控制副翼、扰流板和升降舵的载荷减缓控制系统,通过自动偏转副翼和扰流板,抵消阵风干扰带来的影响,并通过偏转升降舵,确保飞机的稳定控制。根据系统性能指标选择合适的参考模型,并设定合理的目标函数。最后,应用了IM-PSO算法进行控制器参数的自动寻优。仿真结果表明,基于IM-PSO优化的载荷减缓控制系统,能有效降低阵风干扰,改善飞机的乘坐舒适性,达到了良好的控制效果。
Civil aircraft in the vertical turbulence interference, will have an undesirable overload, resulting in reduced ride quality. In response to this problem, a load mitigation control design scheme based on IM-PSO optimization is proposed. A load mitigation control system is designed to control ailerons, spoilers and elevators. By automatically deflecting ailerons and spoilers, the effect of gust disturbance is eliminated and the aircraft’s stability control is ensured by deflecting the elevator. According to the system performance index, select the appropriate reference model, and set a reasonable objective function. Finally, the IM-PSO algorithm is applied to automatically search the controller parameters. The simulation results show that the IM-PSO-based load mitigation control system can effectively reduce the gust disturbance and improve the ride comfort of the aircraft, achieving good control effect.
