Abstract

The invention provides a differential quantization feedback controller in an aircraft and a control method thereof. The differential quantization feedback controller includes a flight trajectory quantizer, a digital communication network, a differential signal estimator, and a flight controller connected in sequence. The flight trajectory quantizer is connected to the target tracking system to quantify the aircraft flight trajectory detection signal output by it; the digital communication network is used to perform source coding and channel coding on the quantized value generated by the flight trajectory quantizer, and then transmit it to the differential through a wireless channel. The signal estimator; the differential signal estimator is used to receive the differential signal information sent by the digital communication network, and generate a differential estimation signal; the flight controller is connected to the differential signal estimator to realize the control of the flight power system. The invention can realize the automatic navigation network control of the aircraft, effectively reduces the requirement on the information transmission rate of the digital communication network, solves the problem of limited network bandwidth, and is especially suitable for the automatic navigation control of the 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...
