摘要:

对非线性飞行控制系统的非线性鲁棒动态逆设计方法作了研究,给出了一种具有鲁棒稳定的非线性动态逆控制方案,以克服飞机在机动飞行时,被控对象参数不确定性和外干扰对系统稳定性的影响,并给出了该方案在这种情况下的稳定性结果。

Abstract:

The designing approach of nonlinear robust dynamic inversion for flight control systems is discussed, and a new control strategy with robust stability is presented, which will be needed to account for uncertain effects related with unknown parameters and external disturbance while in supermaneuver flight, and a stability result is got about this control strategy in case of parameters perturbation.

Key words: flight control systems, nonlinear control, nonlinear robust control, robust compensation, parameter uncertain
