一种微小型无人飞行器系统的建模与仿真
摘要
建立了微小型无人飞行器的数学模型
并利用小扰动原理对此非线性强耦合系统进行了线性化处理
由于传统的PID控制是建立在线性化模型的基础上的
无人机的飞行有各种不确定性
这便需要一种鲁棒性强的控制算法。采用了H2/Hinf控制算法
得到了较好的仿真结果
验证了这种算法在无人机中应用的优越性。
Abstract
The mathematical model of ducted fan UAV is established based on the exact analysis of dynamic characteristic.As the serious coupling and nonlinear of this model
it is simplified by the theory of small perturbation.The traditional PID control depends on the linear of the model
meanwhile the vehicle has many uncertainty factors.A strategy with better robust is put forward.H2/Hinf strategy is introduced into the control of the ducted fan UAV
and its advantage is proved by the simulation results.
