摘要
根据内外回路思想结合鲁棒H∞回路成形方法,设计了直升机双回路飞行控制系统。内回路主要完成直升机的全姿态控制,包括滚转角、俯仰角和偏航角的同时控制;外回路在内回路的基础上实现了速度跟踪。所设计的控制系统基本实现了直升机各通道间的解耦,且具有良好的跟踪性能和鲁棒性能。最后,按照ADS-33E标准对飞行性能进行了评估,结果表明飞行品质达到了1级水平。
The double-loop flight control system of helicopter was devised,according to the thought of inner and outer loops and H∞loop shaping.The inner loop mainly controlled all the helicopter attitudes including the roll angle,pitch angle and yaw angle simultaneously,while the outer loop realized track of the velocity.The control system realized the decoupling of channels of the helicopter,showing the good tracking performance and robustness.Simulation results show that the flight qualities are the 1st level,according to the ADS-33E standard.
