摘　　要：为使MG150/345-WD型采煤机滚筒高度调整精度达到系统要求,给出了滚筒高度控制原理及系统数学模型,基于Simulink搭建了采煤机滚筒高度仿真模型,分别采用遗传算法和模糊算法对滚筒高度PID控制器参数进行优化,对比了滚筒高度控制性能。研究结果表明:相比遗传算法,基于模糊算法优化的系统在滚筒上调时,响应曲线超调量缩小了34%以上,调整时间下降了28%以上,稳态误差降低了23%以上;在滚筒下调时,响应曲线超调量缩小了24%以上,调整时间下降了23%以上,稳态误差降低了25%以上。In order to make the adjustment accuracy of MG150/345-wd shearer drum height meet the system requirements,the drum height control principle and the system mathematical model are given.Based on Simulink,the simulation model of shearer drum height is built.The parameters of drum height PID controller are optimized by using genetic algorithm and fuzzy algorithm respectively,and the drum height control performance is compared.The research results show that:compared with genetic algorithm,the control performance of drum height is better Algorithm,based on the fuzzy algorithm optimization system in the drum up,response curve overshoot reduced by more than 34%,adjustment time decreased by more than 28%,steady-state error reduced by more than 23%;in the drum down,response curve overshoot reduced by more than 24%,adjustment time decreased by more than 23%,steady-state error reduced by more than 25%.
