摘要
钢化玻璃应力在线检测是钢化玻璃生产过程中的重要环节,其难点在于实现对加载力的高精度快速控制。针对钢化玻璃在线应力检测中对力加载系统快速性和强鲁棒性的要求,提出了一种基于自抗扰控制技术(ADRC)的钢化玻璃在线力加载控制策略,在建立力加载系统的动力学数学模型基础上,设计了3阶自抗扰控制器,并通过仿真和试验对所设计的控制策略进行了验证。仿真及试验结果表明,所设计自抗扰在线力加载控制策略能够有效地抑制内外扰动的影响,相比于传统PID控制响应速度更快、控制精度更高,符合工业生产中钢化玻璃应力在线检测的要求。
On-line stress detection is an essential part for the tempered glass production line,and the difficulty lies in achieving high-precision and fast control of the force loading.This paper proposes an on-line force loading control strategy,to satisfy the requirements of the rapid and strong robustness of the force loading for tempered glass via Active Disturbance Rejection Control(ADRC)technology.Based on the dynamic mathematical model of the force loading system,a third-order ADRC controller is designed,and the designed control strategy is verified by simulation and experiments.The simulation and experimental results show that the designed on-line force loading strategy can effectively suppress the influence of internal and external disturbances,which is faster than the traditional PID control and has higher control precision.In short,it meets the requirements of online stress detection of tempered glass in industrial production.
