【摘要】 为了研制出适合我国国情的具有自主知识产权的棒线材无头轧制系统,对棒线材无头轧制系统的组成及工作机理进行了分析和研究,建立了一套棒线材无头轧制系统虚拟样机,设计了基于PROFIBUS总线的棒线材无头轧制控制系统,提出了基于同步误差补偿的焊机移动控制的控制策略,并用单神经元复合控制器结合人工免疫调节机制对该系统闪光焊机的移动控制进行了仿真.仿真结果表明:单神经元复合控制可以有效地提高焊机对轧制坯的同步跟踪精度,人工免疫反馈机制可显著增强焊机的抗干扰能.更多还原

【Abstract】 To develope an endless-bar rolling system (EBROS) with our own sciential property right,the component of EBROS and its working principle are analyzed and developed in this paper,its virtual system is established,and its control system is designed based on PROFIBUS. The control strategies of billet flash-butt welding and welder moving are put forward,and the moving control of welding machine is simulated by combining a single neural network controller and an artificial immune adjuster. Simulating results show that a com- posite controller of single nerve-cell can effectively increase the synchronously tracking precision of welding machine to rolled-billet,and the introduction of an artificial immune adjusting law in the driving system of welding machine can obviously enhance its property of outside disturbance resistance.更多还原
