摘要
以双直线电机驱动进给机构为被控对象,以配套的SIMODRIVE611D为控制系统,建立了伺服系统的数学模型,给出了直线电机电流与切削力的关系,确定了以直线进给轴电机驱动电流为反馈对象、以进给速度为控制输出量的控制原理。围绕进给轴恒电流加工控制目标,选择了模糊控制作为直线驱动进给加工过程的控制方法。结果表明模糊控制有更快的响应时间和更好的抗干扰性,并可有效地保护刀具和提高20%的铣削加工效率。
Taking the feed-driven linear motor mechanism as the control object, the SIMODRIVE 611D as the control system, to establish mathematical model of the servo system. The relation between feed-axis current and cutting force is presented, the current and feed-rate are separately selected as feedback and output. Around the aim of the feed-axis constant current control, choose the fuzzy control as the control method of the linear feed-driven machining process. The simulation results indicate that the intelligent control system has fast response time and good performance of anti-jamming, also the efficiency of milling can be improved 20% and tool be highly protected.
