Abstract

The present invention proposes a segmented corrected barometric altitude estimation method, which fuses the GPS altitude information obtained by the GPS device and the atmospheric pressure obtained by the gas pressure sensor, and uses the real-time GPS altitude data and barometric altitude data in the segmented interval Fitting is performed to obtain the feed-forward correction formula of the real-time barometric altitude information. On this basis, the correction barometric altitude is calculated according to the correction formula, and then the feedback correction error is calculated according to the GPS altitude data, so as to obtain the complete barometric altitude correction formula. The present invention provides accurate barometric altitude information in real time for a system moving within a large altitude range through segmented barometric altitude correction.

Description

technical field [0001] The invention belongs to the technical field of aircraft control, and in particular relates to a method for estimating barometric altitude with segment correction. Background technique [0002] The basic function of the aircraft control system is to ensure the stable attitude of the aircraft through a certain control algorithm according to certain index requirements, and guide the aircraft to the desired position through a given control strategy to complete the established flight mission. At the same time, during the flight, the information exchange between the aircraft and the ground control station is realized. In the aircraft control system, one of the main control objects is the altitude of the aircraft. In order to meet the requirements of specific flight missions and achieve accurate altitude control, the aircraft control system must first be able to obtain information that reflects the current altitude of the aircraft. [0003] Currently, airc...
