井下带式输送机智能调速控制系统设计与研究

针对目前我国矿用带式输送机采用的控制模式大多为开环控制,实际运行过程中输送速度与负载不匹配,造成电能浪费的问题,介绍了一种基于遗传算法改进的模糊PID控制策略,采用主从式结构,实现了输送机智能化调速。通过在MATLAB中仿真实验分析,结果表明:遗传算法优化后的模糊PID控制较传统的PID控制具有更小的超调量、更优的系统抗干扰能力和响应速度,实现了节能控制。同时,组态软件实现了带式传输机运行状态的监控。

Design and Research on Intelligent Speed Regulation Control System for Underground Belt Conveyor

In view of the current control mode adopted by mining belt conveyors in China,most of them are open-loop control.In actual operation,the conveying speed does not match the load,which causes the problem of waste of power.An improved fuzzy PID control strategy based on genetic algorithm was introduced.The master-slave structure was adopted to realize intelligent speed regulation of the conveyor.Through the simulation experiment analysis in MATLAB,the result shows that the fuzzy PID control optimized by genetic algorithm has smaller overshoot,better system anti-interference ability and response speed than traditional PID control,and achieves energy saving control.At the same time,the configuration software realizes the monitoring of the running status of the belt conveyor.
