摘　　要：将伪谱法应用于多无人飞行器(Unmanned Aerial Vehicle,UAV)协同航迹规划,给出了基于Gauss伪谱法(Gauss Pseudospectral Method,GPM)的多UAV协同航迹规划方法。根据UAV的物理特性,结合协同规划的要求,建立了多UAV协同规划的最优控制模型。此模型包括UAV机动性能约束、路径约束、多UAV协同打击约束和集结区约束;利用GPM将最优控制问题转化为非线性规划问题,并用非线性规划软件求解。仿真结果表明,该方法能够满足多UAV的协同规划要求,具有较高的求解精度。Multi-UAV cooperative trajectory planning is studied by using Gauss pseudospectral method （GPM）. First, considering the physical features of UAV and the cooperative planning requirements, an optimal control model for multi-UAV cooperative trajectory planning is proposed, and maneuverability constraint, path constraint, cooperative constraint and rendezvous constraint are analyzed and incorporated in the model. Then, the optimal control model is transformed into a nonlinear programming （NLP） problem by using GPM, and is solved by NLP software. Numerical experiments show that GPM can be used in multi-UAV cooperative trajectory planning and the results demonstrate effectiveness and accuracy of the method.
