无动力飞行器的制导与控制系统

摘要

提出了考虑常值风影响时无动力飞行器的动力学方程.基于变结构控制策略设计了三维的制导律和控制律,以此高度非线性、强耦合、时变的模型为基础进行了六自由度仿真,仿真结果表明这种考虑了风影响的动力学模型更接近实际,制导律和控制律是有效的,具有工程应用价值.%in this paper,a novel complete model of unpowered vehicle was proposed,in which the wind effects are taken into consideration.the wind is modeled as constant velocity and constant acceleration.Based on the variable structure control(VSC)theory,the VSC guidance was presented,in conjunction with the VSC attitude control law,the simulation based on the six-degreeof-freedom model has been performed to verify the performance of the designed guidance and control laws,the simulation results demonstrate that it's valid and it's of practical value.
