hp伪谱法实现滑翔飞行器姿态跟踪控制

Attitude Tracking Control of Gliding Aircraft Based on hp Pseudo-Spectral Method

针对非线性、多约束的滑翔飞行器再入段质点运动学与动力学模型,采用多区间hp自适应伪谱法对滑翔飞行器的再入段轨迹进行优化设计,再将得到的最优控制量进一步解算,得出飞行器最优控制信号,并针对滑翔飞行器滚转通道进行跟踪控制。仿真结果显示,系统能够识别控制信号,并有效实现姿态跟踪,使得飞行器沿最优轨迹再入飞行。

In order to build the kinematics and dynamics models of the reentry segment of a nonlinear and multi-constrained gliding aircraft, the multi-interval hp adaptive pseudo-spectral method is used to optimize the reentry trajectory of the aircraft, and the optimal control quantity is obtained. The quantity is further solved, the optimal control signal of the aircraft is obtained, and the tracking control of the rolling channel of the gliding aircraft is performed. The simulation results show that the system can identify the control signal and effectively realize the attitude tracking, making the aircraft reenter the flight along the optimal trajectory.
