摘　　要：针对飞行控制系统大包线控制律中控制器参数规律难以拟合的问题,提出了一种包线范围内工作点的选择方法和按动压调参的控制器参数范围设置方法,按本方法所选择的工作点在包线范围内分布均匀,控制器参数随动压单调变化,便于拟合。为证明本方法的有效性,以某型运输机为例,对纵向控制增稳系统中的参数进行了调参规律拟合。仿真结果表明,所得控制律在整个包线范围内都具有良好的动态响应。To solve the problem that parameters in the control law of the large envelope are difficult to fit, the working point selecting method and the setting method of the controller parameter＇ s scope are proposed in this paper. The working points selected by this way distributed uniformly in the envelope, and the gotten parameter can change with dynamic pressure in a monotone form （monotone increasing or descending）, it is ease to fit. To test the validation of this method, the simulation, which is based on a longitudinal control augmented stability system of a type of transport plane, is done. The result of simulation shows that the control law gotten by this way has good performance in the whole envelope.
