Abstract

The invention provides a differential quantization feedback controller in an aircraft and a control method thereof. The differential quantization feedback controller comprises a flight track quantizer, a digital communication network, a differential signal estimator and a controller in sequential connection, wherein the flight track quantizer is connected with a target tracking system, and quantizes output aircraft flight track detection signals; the digital communication network is used for performing source coding and channel coding on the quantization value generated by the flight track quantizer, and then transmits the result to the differential signal estimator through a wireless channel; the differential signal estimator is used for receiving differential signal information sent by the digital communication network and generating differential estimation signals; and the controller is connected with the differential signal estimator, and realizes the control on a flight power system. The aircraft automatic navigation networked control can be realized; the requirement on the information transmission speed of the digital communication network is effectively reduced; the problemof network bandwidth limitation is solved; and the differential quantization feedback controller and the control method are particularly suitable for the automatic navigation control of a supersonic aircraft.

Description

technical field [0001] The invention relates to the technical field of automatic navigation networked control in aerial vehicles, in particular to a differential quantization feedback controller in an aircraft and a control method thereof. Background technique [0002] In recent years, technologies such as informatization, networking, automation, and intelligence have been widely used in aircraft automatic navigation systems, such as navigation control systems for drones and loitering bombs. The wide application of new technologies has promoted the development of automatic navigation technology. In this type of aircraft automatic navigation system, information transmission is realized between the ground base station and the aircraft through a digital communication network, and the aircraft can realize automatic navigation through networked control. This kind of networked control problem has received more and more attention. [0003] In this aircraft automatic navigation ne...
