摘要
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。
Using the theory of nonlinear dynamic inversion control and the natural time scale separation between fast and slow dynamics of the bank to turn (BTT) missile, a nonlinear autopilot design method for BTT missile is presented based on the simplified control design model. According to the practical flight height and speed of the BTT missile, the nominal aerodynamic coefficients of the missile can be calculated. The nonlinear autopilot is just based on these nominal aerodynamic coefficients, and hence it is suitable for control of BTT missile in the entire flight envelope. Six degrees of freedom simulation results have shown the rightness and effectiveness of the proposed scheme.
