摘　　要：针对离散时滞随机线性系统的结构特点,探讨了不同情况下的最优控制算法。当受控对象各控制通路中滞后时间间隔都相同,且输入为随机信号时,可采用二次函数型最优控制定律和分离定理。而对于滞后间隔不断变化的复杂系统,可采用滞后补偿器原理。在极限情况下,这些方法还可推广到连续系统。通过例子可以看到算法并不增加系统状态变量的维数。in allusion to structure characteristic of the random linear system with time lapse dispersed, we discuss the superior control calculate way in different case. The interval of the time lag is identical of each lane controlled and when the input is a random sign, we can adopt quadratic function of optimum control and separation theorem. For the complicated system in which the lag- intervals change constantly, we can adopt dement of lag compensator. Under the limit circumstance, these methods can also expand to the continuous system. By the example ,We can see that the algorithm put forward in this paper does not increase the system state variable of dimension.
