Abstract

The invention discloses a controller design method for displaying and considering dynamic characteristics of an aircraft actuating mechanism. The method comprises the following steps: considering thedynamic characteristics of the actuating mechanism, and establishing an aircraft actuating mechanism kinetic model; decomposing an aircraft longitudinal control model into a speed control theoreticalmodel and a height control theoretical model; deducing a function of the aircraft fuel equivalent ratio phi as a speed controller by taking the aircraft fuel equivalent ratio phi as a controlled variable and adopting a dynamic inverse control method according to the speed control theoretical model, and determining parameters of the speed controller; combining a height control theoretical model with the aircraft actuating mechanism kinetic model to obtain a height control theoretical model considering the dynamic characteristics of the aircraft actuating mechanism, and converting the height control theoretical model into a height control theoretical model in a strict feedback form; taking the voltage for controlling the tail vane to deflect as a control quantity, deducing a voltage functionfor controlling the tail vane to deflect as a height controller by adopting a backstepping control method, and determining the parameters of the height controller.

Description

technical field [0001] The invention relates to a controller design method showing consideration of the dynamic characteristics of an aircraft actuator, which belongs to the field of aircraft controller design. Background technique [0002] The unknown disturbance caused by the complex flight environment of supersonic vehicles, the strong coupling caused by the integration of the engine and the fuselage, and the elastic deformation caused by the slender and lightweight materials all bring great challenges to the establishment of the model. Previously in the literature, different modeling methods and a variety of reasonable assumptions were used for hypersonic vehicles to obtain six degrees of freedom and longitudinal control models of the vehicle. However, the dynamic characteristics of the empennage are not fully considered in these models. In actual engineering, the dynamic characteristics of the actuator, such as bandwidth, damping ratio and oscillation frequency, seriou...
