Abstract

The invention discloses a modeling method and a modeling device applied to a high-altitude vehicle system. The method comprises the following steps: simplifying a physical model of the high-altitude vehicle system to be a double-rigid-body system, wherein an aerostat and a pod are simplified to be one rigid body; determining generalized coordinates of the high-altitude vehicle system, wherein thegeneralized coordinates at least comprise attitude angle information of each rigid body in the high-altitude vehicle system; solving a lagrange function of the high-altitude vehicle system and building a lagrange equation; and determining the attitude angle information of each rigid body in the high-altitude vehicle system according to the built lagrange equation. The method and the device provided by the invention solve a technical problem that a result of modeling and simulation for the high-altitude vehicle system has larger error relative to actual conditions in the related technologies.

Description

technical field [0001] The invention relates to the field of simulation modeling and analysis, in particular to a modeling method and device applied to high-altitude aircraft systems. Background technique [0002] The high-altitude aircraft system includes an aerostat and a pod flexibly connected to the aerostat. The aerostat can be a balloon, an airship, etc., and the pod is usually a load compartment. The aerostat and the pod are usually connected by a rotary connector or a system. Rope and other spherical hinge connections. In the design and flight process of the high-altitude aircraft system, the dynamic model of the high-altitude aircraft system is the focus and basis of the control system design, and the dynamic performance determines the performance indicators that the high-altitude aircraft system can achieve. At present, when modeling the high-altitude aircraft system, the aerostat and the pod are usually regarded as a whole, and the classical Newtonian mechanics m...
