基于飞行品质的飞机控制增稳系统参数估计

提出了一种控制增稳系统参数的设计方法,即利用低阶等效系统和飞行品质边界,通过搜索算法确定满足对应飞行品质的参数集合,再利用多种飞行品质确定的参数集合的交集和数据的插值算法,确定控制增稳系统的控制律参数。通过纵向增稳系统设计仿真表明,所提方法简化了传统设计方法通过性能指标反复选择参数和验证系统飞行品质的过程,为控制增稳系统的设计提供一种简单有效的方法。

Parameter Estimation for Control Augmentation System Based on Handling Quality Requirements

This paper proposes a method to design parameter of control augmentation system.This method makes use of low order equivalent matching system and the boundary of handling quality to confirm the collection of certain parameter.Then it will design the parameter through the search algorithm and the intersection set of some handling qualities.Last,simulation of longitudinal control augmentation system shows that it′s a simple and effective method.The method simplifies the process of the designation of flight control system without choosing the parameters and verifying the handling qualities repeatedly.
