摘要
针对煤矿井下刮板输送机链条张力控制的非线性、随机性和时变性特点,提出了一种基于滑模控制的刮板输送机链条张力控制方法来改善张力控制系统的动态性能。该方法采用指数趋近律,使系统在一定特性下沿规定状态轨迹运动。仿真结果表明,采用该方法的控制系统动态特性好,鲁棒性及抗干扰能力强。
According to nonlinear,stochastic and time-varying characteristics of chain tension control of scraper conveyor in coal mine underground,a chain tension control system of scraper conveyor was proposed which was based on sliding mode control method to improve dynamic performances of tension control system.The method adopts exponential reaching law to make the tension control system run along prescriptive state trajectory in a certain characteristic.The simulation results show that tension control system based on the method has good dynamic characteristics,strong robustness and superior interference immunity.
