摘　　要：通过对包含多率采样信息的状态变量设计一个预定义的线性函数,进而来实现状态反馈控制。基于此,该预定义函数表示为以更快的输出采样系统得到的输出向量的线性组合。该方法也可应用于不可观测模式的系统。最后,通过仿真实验说明本文所提方法的有效性。In this paper,by designing a pre-defined linear function for the state variables containing the information of multirate sampling,the state feedback control is finished.Based on this,this predefined function should be represented as a linear combination of output vector which is obtained by a faster rate output sampling system.This method can also be applied into systems with unobservable modes.The proposed method has the advantage that the number of output samples required can be less than the observability index.Finally,the effectiveness of the proposed method is demonstrated by simulation experiments.
