调参控制规律是目前先进飞行器控制系统设计中受到重视的一种控制方案。为了简化控制规律,减少调参所必需的传感器和测量线路,本文采用了调二次型加权阵的极点配置法来进行鲁棒最优系统的设计。该设计方法在性能损失最少的前提下,找到一组闭环增益,既避免了对多飞行状态的调参处理,又可确保在各飞行状态下,系统都具有所要求的闭环极点位置。本文还利用该方法对某型飞机的纵向控制增稳系统,在九个飞行状态下,进行了鲁棒最优设计。其响应、俯仰速率和法向加速度的阶跃响应表明,这种方案的设计效果是令人满意的。 Regulated control law is the most advanced control scheme in aircraft control system. In order to simplify the control law and reduce the sensor and measurement line necessary for the parameter adjustment, this paper adopts the pole placement method of the quadratic weighted matrix to design the robust optimal system. The design method finds a set of closed-loop gains with least loss of performance, which not only avoids the adjustment of multi-flight conditions, but also ensures that the system has the required closed-loop pole position under each flight condition. In this paper, we also use this method to make a robust optimal design of a certain aircraft longitudinal stability control system under nine flight conditions. The step response of its response, pitch rate and normal acceleration shows that the design effect of this scheme is satisfactory.
