为研究采煤机滚筒在不同复杂工况下的位置跟踪控制，以液压机构的工作原理为基础，建立了滚筒液压调高机构的数学模型。基于自适应模糊微分积分滑模鲁棒性强的优点，提出了在鱼群－蚁群融合算法优化滑模控制器参数条件下的滚筒位置跟踪控制方案，并分析了滚筒在采用一般滑模控制器及自适应模糊微分积分滑模控制器下位置跟踪的特点。仿真结果表明：采用结合融合算法优化的自适应模糊微分积分滑模控制器的滚筒调高机构对内部参数摄动及外部时变干扰具有较好的鲁棒性，能够实现位置跟踪控制。

Based on the principle of hydraulic mechanism, a mathematical model of hydraulic drum height adjustment was estab?lished for the study of position tracking estimates of shearer’ s drum working under various and complicated circumstances. The drum position tracking scheme, in which the fusion algorithm of artificial fish swarm algorithm and ant colony algorithm ( AFSA?ACA) was a?dopted to optimize the parameters of the sliding mode controller, was proposed on the basis of robust advantages of adaptive fuzzy differ?ential and integral sliding mode control ( AFDI?SMC) , and the specific working characters with both general and adaptive sliding mode control were also analyzed. Simulation results illustrate that the adaptive control system is reliable in both occasions and capable of a?chieving better position tracking control with good robustness.
