摘要
以运输型直升机为研究对象,根据飞行品质规范ADS-33E的要求,设计直升机俯仰、滚转、航向和高度通道的理想模型;利用状态反馈方法,针对不同高度和速度下的飞机模型,设计显模型跟随控制律;拟合包线内的控制器参数,实现显模型跟随调参控制律。最后,系统仿真试验结果表明,采用这种控制方案可以取得良好的控制效果,验证了该方法的可行性和有效性。
According to the handling qualities requirements of ADS-33E, this paper takes a transport helicopter as the research subject, in which the ideal model on the conditions of the pitch, roll, heading and height channels are devised. With the method of state feedback, the explicit model following control law for the helicopter models at different height and speed is given. For the controllers ＇ parameters in flight envelop has been fitted, the explicit model following control law with adjustable parameters is a- chieved. At last, the simulation results show that the proposed control method can obtain the satisfied effect, and this method is feasible and effective.
