针对一类线性系统的圆盘极点配置问题,提出了执行器各条通道增益偏差容忍区间的概念。利用执行器单一通道增益偏差模型,给出了在圆盘极点配置问题中执行器通道增益偏差容忍区间的算法。硬件设计者可以根据执行器每条通道的增益偏差容忍区间,来判断出每条通道对闭环系统影响的重要程度,再根据其重要程度大小来加强该通道的硬件冗余度。为圆盘极点配置问题中执行器通道的硬件冗余设计提供了重要理论依据。一个CH-47双旋翼直升飞机实例仿真说明了所给出方法的有效性。
Aiming at the problem of disk pole placement for a class of linear systems, the concept of tolerance tolerance interval of each channel of actuator is proposed. By using the single channel gain deviation model of actuator, the algorithm of tolerance tolerance of actuator channel gain in the disk pole placement problem is given. The hardware designer can determine the importance of each channel’s influence on the closed-loop system according to the tolerance tolerance interval of each channel of the actuator, and then strengthen the hardware redundancy of the channel according to its importance. It provides an important theoretical basis for hardware redundancy design of actuator passage in the disk pole configuration. A CH-47 bi-rotor helicopter simulation shows the effectiveness of the proposed method.
