摘　　要：针对采煤机滚筒调高机构的特点,即定量、开关式控制液压系统,分析了记忆程控——预知控制结果的再现控制的特征。给出了滚筒调控静态数学模型,并根据调高机构的调控特征方程与采样点间顶底板变化特征方程的差异,给出了在其采样区间内的指令式控制策略,其方法的规则条目少、简单易运算、符合实际控制要求。In view of the character of drum lifting frame, invariable value and switch control hydraulic transmission system, this paper analyzes reappearing controlling character of memory program controlling predicted control results. Static mathematic model of drum accommodation and control is presented, and instruction model control strategy of sample intervals is presented based on differences between characteristic equations of lifting frame and characteristic equations of top and bottom board change among the sampling spots, the rules of this method are few, simple, easy to operate and meet controlling demands.
