基于响应类型的直升机悬停状态显模型跟踪控制律设计

Design of Explicit Model-Following Control System of Helicopter Hover State Based on Response Type

现代战场使用环境对直升机的飞行品质要求越来越高,使用电传飞控系统可大幅改善直升机的飞行品质,本文以电传飞控系统为研究对象,进行面向特定任务的具体指标要求的控制律设计。首先,根据ADS-33E飞行品质规范要求构造出满足悬停状态下俯仰轴ACAH响应等级1要求的指令模型;其次,以该指令模型构建显模型,通过反馈补偿算法进行跟踪偏差修正的模型跟踪控制律设计,最终得到整个闭环系统俯仰姿态满足飞行品质等级1要求的控制律构型和参数。通过MATLAB仿真验证了该设计方法的合理性和有效性。

The requirements of handling qualities for helicopter is becoming higher and higher due to modern war field environment.Using of fly-by-wire control system can improve handling qualities substantially.The paper designed a flight control law for fly-by-wire system to specific quality requirement of given task.Firstly,construct dictation model witch satisfy ACAH response level 1 according to ADS-33E flying quality requests.Secondly,constructs explicit model using dictation model,designed deviation correction control law throw feedback compensation algorithm.Finally,get the whole closed loop system configuration and parameters which makes pitch attitude meeting flying qualities requests level 1.MATLAB simulation validated the rationality and validity of the design method.
