基于简化的ＢＴＴ导弹控制设计模型，应用非线性动态逆和时间尺度分离方法设计了一种非线性ＢＴＴ导弹自动驾驶仪。根据导弹实际的飞行高度和飞行速度，可以计算出导弹动力学系数的标称值，非线性动态逆法正是基于这些动力学系数的标称值，故适合于控制导弹作大空域飞行。六自由度仿真结果进一步验证了该方法是正确的与有效的。 Based on the simplified BTT missile control design model, a nonlinear BTT missile autopilot is designed by using nonlinear dynamic inverse and time-scale separation method. According to the actual flight altitude and flight speed of the missile, the nominal value of the dynamic coefficient of the missile can be calculated. The nonlinear dynamic inverse method is based on the nominal values ​​of these dynamic coefficients and is therefore suitable for controlling the missile for large airspace flight. Six degree of freedom simulation results further verify that the method is correct and effective.
