零点配置和飞行器高度动态系统的性能补偿

Zero Appointment and Blance of Aircraft High Dynamic System Performance

对于单输入 -单输出系统 ,它的零点取决于系统的输出函数。现试图在系统的输出端并联一个常数阵 ,通过利用可观测性阵讨论它对可观测性性能的影响。证明了在满足适当的条件下 ,可以任意配置零点 ,从而可以将一个非最小相位系统变成最小相位的系统。并成功地将这种设计方法用于飞机的高度动态性能补偿。对飞行员来说 ,了解这种性能是很重要的 ,尤其是在低空飞行的时候。

For single input single output linear system, its zeros were determined by the output function of system. Now we try to parallel connect a constant matrix in the output port. By using of observability matrix, we debate the influence it does on observability performance. We verified that under some condition arbitrary zero assignment could be done. So one non-minimum phase system can be changed into minimum phase system. Moreover, we successfully use this design method for the compensating the performance of plane height dynamic system. It is very important for pilots to know this non-minimum phase characterization particularly when flying in lower level.\;
