【摘要】 将虚拟仪器技术应用于四辊可逆轧机AGC控制系统,介绍控制系统组成及工作原理,设计控制策略;采用数字位置式PID控制算法,较好地实现了系统控制性能。利用虚拟仪器LabVIEW支持的多线程技术,将数据采集与控制置于同一进程,并置为最高优先级,有效实现了系统的实时控制,可达到控制要求。更多还原

【Abstract】 Applys virtual instrument LabVIEW in four reverse rolling mill,introduces the structure and working principle of AGC,and designs control strategy.Digital PID used as controller gains good control effect.Virtual instrument LabVIEW supports multithread,data acquisition and control unit is set in the same thread and maximal priority,as a result,AGC realizes the real time control of system and reach the control request.更多还原
