飞行器最优时滞反馈控制器设计

在设计飞行器最优反馈控制时,针对系统具有控制时滞的特性,采用连续状态变换思想,将具有时滞的控制系统转化为无时滞的控制系统,求使得无时滞控制系统性能指标最小的解，利用这个解去求原系统的状态函数,进而得到时滞反馈控制与状态变换后最优控制之间的关系,求出最优时滞反馈控制的增益。对某型无人直升机实验所得的悬停数据进行仿真验证,仿真结果证明了所提方法的有效性。

Design of aircraft optimal time-delay feedback controller

Since a system has a characteristic of control delay during the design of the aircraft optimal feedback controller, the delay control system is transformed to a non delay control system by utilizing the continuous states transform method.Then using the solution of the non-delay control system,which makes the performance index smallest,the state function of the original system can be calculated. With the help of relationship between the delay feedback control and the state transformed optimal control, it can help find the gain of the optimal time delay feedback control. Simulation is made to verify the hovering data of unmanned helicopter experiments and the results validate the proposed control method.
