| 摘 要： | 为解决折叠翼飞行器在发射段各项特性变化较大、对飞行控制律鲁棒性要求较高的问题,设计了一种以块控反步法为基础的自适应鲁棒非线性控制器.在发射段动态模型基础上,该控制器采用径向基函数( RBF)神经网络自适应逼近飞行器特性变化时的系统未知不确定性和干扰,通过在虚拟控制律中引入动态面控制技术避免多重微分运算,克服了传统反步法...

| Abstract: | The characteristics of a folding-wing aerial vehicle undergo fairly great changes during its launching time.To fulfill the high robustness requirements of a flight control system,an adaptive robust nonlinear flight controller based on block backstepping is designed.A variable dynamic model is established,and the unknown uncertainty and disturbance caused by aerodynamic characteristic changes are adaptively approximated by radial basis function(RBF) neural networks.Dynamic surface control is employed to repl... |
