【摘要】 研究了控制能量约束下单输入多输出系统跟踪误差的最优估计问题。针对上行和下行通信信道的数据丢包进行了分析,并得到最小跟踪误差的显示表达式。研究结果表明对于单输入多输出系统,跟踪误差的最小值依赖于被控对象的结构特征及参数输入信号的统计特性。并且数据丢包在一定程度上会恶化系统的跟踪性能。最后通过实验仿真验证了理论分析的结果。更多还原

【Abstract】 In this paper, the optimal estimation of tracking error for single-input multiple-out(SIMO) systems under control energy constraints is investigated. The packet-dropouts in the upstream channel and down channel are adequately considered. The minimal tracking error is obtained by searching through all stabilizing controllers. The main results of this paper show that the optimal tracking performance in these kinds of system is closely dependent on the structure of the given plant and statistic characteristics of the reference signal. Furthermore, the packet-dropouts in the communication channel will degenerate the tracking performance. Finally, a typical example is given to illustrate the theoretical results.更多还原
