摘要
为解决煤矿井下悬臂式掘进机截割头位置控制精度差、响应速度慢、抗干扰能力差等问题,以EBZ200型悬臂式掘进机为研究对象,通过数学模型构建以及计算机模拟仿真等方式,构建了截割头运动位置数学模型以及液压系统数学模型,提出SOA-PID控制算法,对传统PID算法进行优化。通过对两种算法控制系统阶跃响应效果进行对比,得出SOA-PID算法控制精度提升63%,响应速度提高38%,系统的控制精度、响应速度以及抗干扰能力明显提升。
In order to solve the problems of poor control accuracy,slow response speed,and poor anti-interference ability of the cutting head position of the boom roadheader in coal mines,the EBZ200 boom roadheader was taken as the research object.Through mathematical model construction and computer simulation,a mathematical model of the cutting head movement position and a mathematical model of the hydraulic system were constructed.The SOA-PID control algorithm was proposed to optimize the traditional PID algorithm.By comparing the step response effects of two algorithm control systems,it was found that the SOA-PID algorithm improved control accuracy by 63%and response speed by 38%.The system’s control accuracy,response speed,and anti-interference ability were significantly improved.
