Abstract

An aircraft attitude output feedback control method and system, controller and control method based on input and output quantization, establishing an aircraft dynamics model and an attitude model containing quantized input, introducing auxiliary variables, and converting the aircraft-based model containing input quantization into The extended state aircraft model with state quantification, using the output quantification information, designs the state observer, and designs the attitude output feedback control scheme of the aircraft system based on the state estimation value, which can effectively reduce the amount of information in the communication channel and save system resources. Attitude control of modular aircraft linked by wireless network.

Description

1. Technical field [0001] The invention relates to an aircraft attitude output feedback control method and system, a controller and a control method, in particular to an aircraft attitude output feedback control method and system based on input and output quantification, a controller and a control method. 2. Background technology [0002] In recent years, attention has been paid to modular spacecraft. Modular spacecraft adopts a modular open network architecture. Using the basic idea of ​​plug-and-play system, each component of the spacecraft is modularized and assembled, which can reduce the cost of the spacecraft. Speeds up assembly and facilitates easy removal and replacement of defective or obsolete components. The core technology of modular spacecraft is wireless data communication and wireless power transmission, which is different from the traditional cable interconnection that is bulky, bulky, and inflexible. Under this technology, all functional parts of the spacecr...
