Abstract

The invention discloses a sliding mode control method of a reusable delivery system based on an event trigger mechanism, which simplifies the reusable delivery system into a second-order linear system, and uses the intelligent method of sliding mode control to effectively solve the problem of constant operating environment of the system. The problem of changing, to obtain ideal dynamic characteristics, has certain robustness to system parameters and external interference signal changes, so that the system has good stability; in addition, an event-triggered communication mechanism is introduced to reduce the transmission data in the network and alleviate It reduces the burden of network bandwidth occupancy, saves limited communication resources, and reduces the power consumption of network nodes.

Description

technical field [0001] The invention relates to the technical field of nonlinear system control, in particular to a sliding mode control method of a reusable carrier system based on an event trigger mechanism. Background technique [0002] The reusable vehicle is by far the most complicated flight process. In the re-entry phase, the reusable vehicle needs to pass through the complex flight environment under the condition of a large initial re-entry kinetic energy and potential energy to realize the aircraft It is necessary to make a safe landing, and at the same time, make the overload, dynamic pressure and aerodynamic heating within the allowable range. The reentry flight of a reusable vehicle has the flight characteristics of large airspace and cross-speed domain, and the aerodynamic characteristics change strongly during the flight, which leads to disturbance torque in the external environment, so its control is a difficult task. In addition, it is very important to ensu...
