Model Calibration System and Method Based on Wing Tip Braking Device of High-Lift Control System

Abstract

The invention relates to a model calibration system and method for a wingtip brake device of a high-lift control system, comprising a test design module, a real wingtip brake, a hardware-in-the-loop simulator, an experimental measurement calibration module and a wingtip brake model. The experimental design module transmits the experimental conditions to the real wingtip brake, the hardware-in-the-loop simulator and the experimental measurement calibration module. The experimental measurement calibration module compares the difference between the actual wingtip brake and the dynamic characteristic information of the wingtip brake model, and controls the parameter adjustment of the wingtip brake model through the hardware-in-the-loop simulator until the wingtip brake model meets the accuracy requirements of the working conditions. It can ensure the confidence of model calibration, and can effectively reduce test conditions and human errors, thereby effectively reducing the number of physical verifications and shortening the development cycle and cost of high-lift control system wingtip brakes.

Description

technical field [0001] The invention belongs to the technical field of aviation testing, and relates to a brake model calibration system and method, in particular to a model calibration system and method for large-scale fixed-wing aircraft flaps and slats based on a high-lift control system wingtip braking device. Background technique [0002] With the continuous development of the aviation industry, the life cycle model using the V model is generally adopted. Model-based virtual verification, as one of the activities of the life cycle model of the V model, can play an important role in architecture selection and trade-offs, system integration, verification and confirmation, and can effectively reduce the number of physical verifications, shorten the development cycle and cost, Hosts and suppliers are gradually being applied during the R&D process.

Problems solved by technology

Due to the limited consideration of the mathematical model used in modeling and simulation, it is impossible to accurately simulate the actual operating state of the flap and slat wing tip brakes. There is a large difference between the simulation results and the real dynamic characteristics, which reduces the flap and slat wing tip brakes to a certain extent. Confidence in model simulations, which cannot meet the requirements of model-based virtual verification

[0004] The existing method is to manually calibrate the parameters of the simulation model by means of tests. However, due to the complex dynamic characteristics of the flap and slat wingtip brakes, many operating conditions, and many influencing parameters, in order to ensure the confidence of the model simulation, it is necessary to simultaneously calibrate the flaps and slats. The working envelope of the slat wingtip brake covers as much as possible, so there are many test items, the workload of model calibration is huge, and it is easy to lose data during the transfer process due to human error, and the process is uncontrollable
