高动态无人飞行器轨迹规划与控制技术

针对高动态无人飞行器的飞行环境中,气动力、气动热条件苛刻,飞行参数和结构变化剧烈的特点,研究了多约束条件下的轨迹规划与设计方法.提出了以无人飞行器倾侧角为主控制量,将轨迹规划问题转化为最优控制问题,采用极大值原理和改进的邻近极值法,求解无人飞行器总吸热量最小的最优控制,并使得最优控制满足所有飞行边界约束和终端约束.最后,以某型高动态无人飞行器为对象,仿真证明了方法的有效性.

Trajectory planning and control for high-dynamic unmanned aerial vehicles

According to the strict aerodynamic heating and force environment,which had the characters of strong uncertainty of flight parameters and structure,the planning and optimization of multi-constraints trajectory were studied for high-dynamic unmanned aerial vehicle(UAV).The attack angle and the bank angle were the control parameters of high-dynamic UAV and the bank angle was taken as the main control parameter in the proposed method.Hence the optimization of trajectory was cast as the optimal control problem....
