摘　　要：本文针对离散状态时滞系统,首先将其变形为无时滞形式,设计出最优控制器;然后运用离散提升技术对输入进行多采样,得到扩展的离散系统模型,再运用最优控制技术对扩展系统进行最优设计。最后对系统进行仿真,结果表明,该算法具有较好的控制效果,具有较好的稳定性。To discrete state time-delay system, firstly, it was turned into no-delay form and an optimal controller was designed; secondly the expansion model of the discrete system was got through using discrete lifting technology to sample input with multi-rate sampling, and a optimal controller was designed to the expansion model.Finally,the system was simulated ,the results shows that the algorithm has good control performance and good stability.
