摘要
针对非圆活塞的特殊复杂型线,提出一种基于双通道控制技术的非圆活塞异型截面复合加工的方法。构建双通道系统控制模型,基于Turo PMAC开放伺服算法特性,设计模糊自整定PID算法,提高系统的动态响应特性。建立两通道间信号通讯,运用脉冲同步控制原理,实现双通道系统中主次系统协调控制。最后基于双通道高频往复直线进给实验平台,设计完成两通道间的同步跟随实验。结果表明:跟随实验验证了基于双通道控制技术的非圆活塞异型截面复合加工方法的可行性;在主轴转速范围为0~1 000 r/min内,跟随误差随主轴转速升高而增加。
A method of special section, composite processing of non-circular piston based on double-channel control technique was proposed aimed at complex profile of non-circular piston. The double-channel model of control system was constructed and the fuzzy self-tuning PID algorithm was designed based on feature of Turbo PMAC, open servo algorithm to improve the dynamic response charac-teristic of system. The signal communication was realized between the two channels and the double-channel system, coordinated control in the primary and secondary system was achieved useing the principle of pulse synchronization control. Finally synchronous following test was designed between the two channels based on the experiment platform of double-channeF high frequency reciprocating linear feed. The result shows that the method of special section, composite processing of non-circular piston based on double-channel control technique is viable, and when the spindle speed is 0-1 000 r/min,the following error of processing of non-circular piston increases with increaseed spindle speed.
