摘要
以某型直升机横航向通道为对象， 将 Ｈ∞控制理论与计算方法引入直升机飞行控制系统设计中。通过对灵敏度函数和补偿灵敏度函数频率特性的回路整形， 设计出有较强抗干扰能力和较好鲁棒稳定性的直升机 Ｈ∞控制系统。仿真计算表明， 具有 Ｈ∞控制器的直升机横航向姿态保持系统， 其指令跟踪性和鲁棒稳定性都有了明显的改善。
In this paper, the H ∞ control theory is applied to design the flight control system of the helicopter lateral directional channel.By loopshaping the frequency properties of sensitivity and complementary sensitivity function, the helicopter H ∞ control system with stronger ability of restraining disturbance and better robust stability can be designed. The simulation results show that the ability of command tracking and robust stability in the attitude holding system of the helicopter lateral directional channel with H ∞ controller can be obviously improved.
