Abstract

The invention provides a control-limited airship flight path control method for solving a problem of airship flight path tracking. Via the method, a mathematical model for spatial motion of an airshipis built, the model is a controlled object, limited control of the airship is taken into consideration, and a hyperbolic tangent function is adopted for designing flight path control laws. A closed loop system controlled via the method can be used for stably tracking an instructed flight path, good control precision can be realized, and an effective solution is provided for implement a flight path control program for the control-limited airship.

Description

Technical field [0001] The invention relates to an airship control method, which provides a control method for controlling the three-dimensional track tracking of a restricted airship, and belongs to the technical field of automatic control. Background technique [0002] An airship is a kind of aerospace-type aircraft that relies on a lighter than air gas (such as helium) to provide static buoyancy and relies on a flight control system to achieve low-speed maneuvering and fixed-point parking. It has a long space time, low energy consumption, and cost efficiency. It is widely used in environmental monitoring, land surveying and mapping, earth observation, reconnaissance and surveillance and other fields. It has important application value and broad application prospects. It has become a research hotspot in the aviation field. [0003] Track tracking means that the airship starts from any given initial state, gradually tends to and stably tracks the command track in a given ground co...
