摘要
为提高煤矿开采核心设备液压支架推移作业的控制精度,采用模型预测控制算法对支架推移千斤顶进行控制,设计出模型预测控制器,并通过MATLAB搭建仿真平台分析了推移千斤顶实际输出位移对参考序列的追踪情况。仿真分析结果表明:预测时域N_(P)≥15 T时,推移千斤顶位移输出可以对设定参考值进行无超调平稳追踪,并且预测时域越大其位移追踪所需时间越长。研究结果验证了模型预测控制技术应用到液压支架推移作业过程中具备可行性。
In order to improve the control accuracy of the hydraulic support pushing operation of the core equipment of coal mining,the model predictive control algorithm was used to control the support pushing jack,and a model predictive controller was designed.The simulation platform was built by MATLAB to analyze the tracking of the actual output displacement of the push jack to the reference sequence.The simulation analysis results show that when the prediction time domain is N_(P)≥15 T,the displacement output of the moving jack can track the set reference value smoothly without overshoot,and the larger the prediction time domain,the longer the displacement tracking time.The research results verify the feasibility of applying the model predictive control technology to the hydraulic support moving process.
