|
摘要
针对连铸结晶器人工加渣和机器开环加渣的不足,开发了一种具有实时渣厚检测与反馈控制功能的加渣机器人:即在开环加渣机器人的基础上设计增加激光测距传感器,可获取结晶器内实时渣厚信息,综合考虑当前渣厚、结晶器工作时的耗渣速度和机器人的投渣速度三个因素的耦合关系,构建模糊推理机,对加渣机器人的送料机电系统实现参数自整定模糊PID控制,从而实现结晶器内渣厚的智能控制。仿真和应用结果表明基于参数自整定模糊PID控制的加渣机器人效果好,响应快,能实现保护渣按需投放,有利于节能降耗。
According to the defect of artificial slag adding and slagging in the machine,a slag adding robot with real-time slag thickness detection and feedback control function is developed. That is,on the basis of the open-loop slag adding robot,the laser ranging sensor is applied. Then the real-time information of in-mold slag thickness can be obtained. And the coupling relation of three factors: real-time slag thickness,mold work slagging speed and robot slagging rate are taken into comprehensive consideration. Therefore fuzzy controller is built to realize the Parameter Self tuning fuzzy PID control of the slagging robot feeding electro-mechanical system and achieve the intelligent control of slag thickness in the mold. The simulation and application results show that the slag adding robot based on Parameter Self tuning fuzzy PID control has good effect and quick response. It can realize the protection of slag on demand.
