摘要
对直升机各控制通道间耦合严重的特点,基于前馈补偿方法设计直升机解耦控制系统;分析、比较直升机各通道之间的耦合效应,确定解耦控制器结构;针对不同高度和速度下的飞机模型设计解耦控制律,利用径向基神经网络拟合控制参数,实现全包线范围内的解耦控制律,并仿真验证;依据飞行品质规范ADS—33E可以得出,采用上述控制方案,可以取得良好的解耦控制效果,表明了该方法的可行性和有效性。
According to the characteristics of helicopters which is coupling between control channels, a decoupling control design method based on feed-- forward compensation theory is presented. Analysis and comparison Coupling phenomenon between the helicopter control channels and determine the structure of decoupling controller. The decoupling control law is designed according to the helicopter models in different speed and height. By using RBF neural network, realize the full envelope control law and simulation verification. According to ADS --33E, the control method which the paper proposed, obtaining the satisfied effect in decoupling, is feasible and effective.
