摘　　要：对无人机跟踪地面目标时的飞行控制问题进行了研究。首先对某小型无人机跟踪地面目标时的运动状态进行了建模分析,利用自动控制理论知识设计了相应的控制律,然后采用六自由度非线性运动模型进行了控制律的仿真验证,并且分析了风的扰动对跟踪精度的影响。仿真结果表明,设计的控制律能够控制无人机对地面目标进行可靠跟踪,且对侧风扰动具有较好的抑制能力。A flight control system of UAV is studied. The kinetic of a small UAV tracking ground targets is modeled and analyzed and corresponding control laws are designed based on automatic control theory. The control laws are verified by simulation based on a nonlinear 6-DOF aircraft model. The influence on tracking accuracy caused by side wind is also analyzed and simulated. The simulation results indicated that with the application of these control laws, the UAV can continuously tracking ground targets, and have good resistance to side wind disturbance.
