坐标转换理论及其在半实物仿真姿态矩阵转换中的应用术
Coordinate Transformation with Application in HWIL Simulation
摘要
Abstract
The relationship between the direction cosine matrix (DCM) in the space field and DCM in the aeronautics field is derived,to meet the demand of hardware-in-the-loop (HWIL) simulation of near space hypersonic vehicle flight control system.Firstly,the coordinate transformation (CT) theory is introduced,and the conversion method between two cartesian coordinate system is Introctuced.As well as the relationship of DCMs between the matrix transformation under two different reference systems is presented.Then,the analyzes the relationship of coordinate frames between the space field and the aeronautics field.How to convert the coordinate frame in the space field to the coordinate frame in the aeronautics field is researched.Finally,the HWIL simulation indicates that the method is correct and feasible.It ensures the HWIL simulation of navigation system of near space hypersonic vehicle.关键词
