在坐标单位矢量导数为非零条件下,通过建立飞行器的转换矩阵及其微分方程,将飞行器的动力学、运动学方程表达得更清晰、简洁。所得结论易于理解动静两种坐标系在时域内的联系,其数学表达式方便用MAT-LAB语言实现,有利于飞行器的建模与仿真。
Under the condition that the vector derivative of the coordinate unit is non-zero, the dynamic and kinematic equations of the aircraft are expressed clearer and concise by establishing the conversion matrix and the differential equation of the aircraft. The conclusions are easy to understand the relationship between the two coordinate systems in the time domain. The mathematical expressions are conveniently implemented in MAT-LAB language, which is good for the modeling and simulation of aircraft.
