摘　　要：张紧装置是带式输送机安全稳定运行的关键设备,由于带式输送机系统的非线性和运行的大滞后性,本文设计一种滑模模糊控制的液压自动张紧系统,在滑模控制切换面的设计中采用模糊逻辑的内插性能,给出了液压系统的原理图,应用matlab对带式输送机的张紧力进行分析,仿真结果表明基于滑模模糊控制的液压张紧装置响应迅速,控制效果好。It is a key equipment for the take-up on a belt conveyor to guarantee safe and stable operation.The mathematical model of the belt conveyor is nonlinear and there is long time delay during its operation.A kind of hydraulic auto take-up of the belt conveyor was designed.The interpolation property of fuzzy logic control was used in the switching surface of sliding mode control.Moreover,the principle diagram of hydraulic servo system was given.The tension force was analysed by using matlab,during the application of the belt conveyor.The simulation results showed that the sliding mode fuzzy controller is characterized by very fast response and is better.
