摘　　要：针对刮板输送机工作时链条张力时变导致整机工作效率低的问题,提出模糊滑模变结构控制的方法进行链条张力调节,通过建立刮板输送机电液伺服控制系统数学模型,得到电液伺服控制系统的状态方程,与设计的模糊切换增益调节的模糊滑模控制规律结合,得到模糊滑模控制函数。利用Matlab及AMESim对刮板输送机模糊滑模控制器进行仿真分析,由仿真结果可知,基于模糊滑模变结构的控制器能有效的调节链条张力大小,实现刮板输送机实时进行链条张力快速、平稳及精确地调整。The fuzzy sliding-mode variable structure control method is proposed to adjust chain tension, which solves the problem of low productivity on scraper conveyors because of the varying of the chain tension at work, and the mathematical model of the electro-hydraulic servo control system is established to get the equation of state, and it is combined with the fuzzy sliding-mode control which is based on the adjustment of handover gain, then the fuzzy sliding mode control function is got. The fuzzy sliding-mode variable structure controller on the scraper conveyor is simulated by Matlab and AMESim, the simulation results show that the fuzzy sliding-mode variable structure controller could effectively adjust the chain tension and realize the fast, smooth and accurate adjustment of the chain tension of the scraper conveyor in real-time.
