数据链指挥下的战斗机H_∞飞行控制器设计

Design of H_∞ Flight Controller for Fighter under Tactical Data-link Command

基于神经网络对数据链指挥下的战斗机提出了鲁棒飞行控制器设计方案.为了克服由于数据链的引入对战斗机飞行控制所带来的不利影响,设计了基于RBF神经网络的鲁棒飞行控制器.通过对神经网络参数在线调整,使飞行控制系统能跟踪期望指令,并满足给定的性能指标.最后将所设计的飞行控制系统用于数据链指挥下的战斗机飞行控制,仿真结果表明所设计的飞行控制系统是有效的.

t An H∞ flight control scheme is proposed based on neural network for the fighter under the command of tactical data-link. For overcoming the influence due to introducing the tactical data-link, the H∞ flight control scheme is presented for the fighter. The online adjusted parameters are introduced to make flight controller system track the expected command signal and satisfy the given performance index. Finally, the availability of the designed robust flight control system is demonstrated through a flight simulation, and the simulation results suggest the H∞ flight control scheme is valid.
