Embodiment Construction

[0098] The accompanying drawings constituting a part of this application are used to provide further understanding of the present invention, and the schematic embodiments and descriptions of the present invention are used to explain the present invention, and do not constitute an improper limitation of the present invention.

[0099] The input saturated airship track control method provided by the invention firstly calculates the error amount from the given command track and the actual track, and then designs the input saturated track control law by selecting the virtual control amount and adopting the backstepping control method. In practical application, the airship track is measured by the integrated navigation system, and the control quantity calculated by this method is transmitted to the actuator to realize the track control function.

[0100] like Figure 1~2 As shown, the airship track control method of input saturation provided by the present invention comprises the f...

Abstract

The invention provides an airship track control method with saturated input. For aiming at a track control problem of an airship of which an executing mechanism has an input saturation characteristic, a spatial movement mathematical model is established. The spatial movement mathematical model is used as a controlled object. A backstepping control method is utilized for designing an input saturation track control law. The airship track control method settles a track control problem on the condition of input saturation constraint of the executing mechanism.

Description

technical field [0001] The invention relates to the technical field of aviation flight automatic control, in particular to an input saturated airship track control method. Background technique [0002] An airship is a kind of floating aircraft that relies on a gas that is lighter than air (such as helium) to provide static lift, and relies on a flight control system to achieve low-speed maneuvering and fixed-point parking. It is widely used in environmental monitoring, land surveying and mapping, earth observation, reconnaissance and surveillance, etc. It has important application value and broad application prospects, and has become a research hotspot in the aviation field. Track control is to control the airship with a specific control law so that it can fly along a predetermined track. The flight mechanics model of the airship has the characteristics of nonlinearity, channel coupling, uncertainty, etc., and the airborne aircraft is easily affected by the disturbance of t...
