Research On Heave Height Measuring Algorithm Simulation By Micro-strapdown Inertial Theory & Its Data Collecting System

During the last phase of auto-landing of Shipborne UAV (unmanned air vehicle)on deck, to make the UAV identify and track, and finally fly into the intercept net fixed on the rear deck of naval ship placidly and accurately, it should be consider the influence of deck on landing. The naval ship, as a three-dimensional object, its complicated tossing movements are the whirligig movements circling space axis. Among them, the heave oscillation of the deck is an important guidance parameter for the UAV's landing in the process of landing. Considering the advantages of MIMU(micro inertial measurement unit),such as its low costs, small size, light weight, high integration and reliability ,which can bear abominable climate environment and mechanical environment ,this paper puts forward a new emulator model for measuring heave height and designs a MIMU data collection system based on SINS theory and MEMS(micro electronic and micro mechanical ) inertial sensors technique.The whole article consists of 6 parts:1.Object of the project and the development background of the relative technique are introduced.2.The theory of the micro inertial heave height measurement is depicted.3.Arithmetic model base on MATLAB/Simulink for micro inertial heave height measurement is offered ,including the result analysis for the simulation.4.The whole hardware design base on ADuC841 single chip of the MIMU data collection system is depicted.5.Software design is introduced.6.Adjusting and error compensation model of the MEMS is depicted.At last,sum-up ,view and enhancement of the system are given.
