基于火箭弹非线性动力学系统的解耦控制

为消除火箭弹在倾斜转弯（BTT）时俯仰与偏航通道的强耦合,根据建立的火箭弹非线性动力学模型,采用微分几何方法和二次Gauss/回路传函恢复（LQG/LTR）设计了一控制系统,给出了控制器的设计。仿真结果表明：侧滑角近似为零,滚转命令能快速响应,设计的解耦控制器有效。

Rocket Projectile Dynamical Modeling and Nonlinear Decoupling Control

To eliminate the intensive coupling between the pitch and yaw channel for the rocket missile in bankto-turn, the control system was designed by using the differential geometry method and linear quadratic Gaussian/ loop transfer recovery （LQG/LTR） according to the nonlinear dynamic model of the rocket missile in this paper. The design of the controller was given out. The simulation results showed that the sliding angle was near zero and the rolling command could be quick response. The decoupling controller designed was effective.
