【摘要】 本文研究了一类具有量测随机丢包的闭环线性离散系统的最优滤波器设计问题,该系统的控制器、执行器、滤波器以及传感器之间是分置的,并采用所构造的滤波器值作为系统的反馈。在最小方差估计意义下,采用正交原理推导得到待定滤波器的参数矩阵。最后给出了算例仿真,仿真得到的滤波均方误差在其理论值周围波动,这说明了本文所提出算法的有效性。更多还原

【Abstract】 This paper deals with optimal filter design problem of a class of closed-loop linear discrete-time system with stochastic measurement packet dropouts,which is divide-and-conquered,whose feedback is state filtering value constructed by the received measurements.In least variance estimate sense,the parameter matrix of the filter to be determined is derived by utilizing orthogonality principle.At last,a numerical example is given,the obtained mean filtering square error is fluctuate around its theoretical value,this illustrate the efficiency of the proposed method.更多还原
