摘要
介绍了三次预真空牙科灭菌器控制系统的研制,用PIC系列单片机作为控制器,实现对密闭容器内汽液混合状态下的蒸汽温度、压力值的采集与控制。硬件电路上实现了温度、压力值的线性化测量,控制策略上采用模糊控制技术,实验结果表明,该控制器可使系统实现无超调、无静差、鲁棒性强等特点。
The controlling system of triple pulse vacuum sterilizer for dental use adopts PIC single-chip computer as the controller. The information related to stream temperature and pressure of the stream and liquid mixture in the hermetic vessel is acquired and controlled. Linearization measurements of the temperature and pressure and fuzzy control technology are all involved in. The experiment result shows that the controlling system makes the sterilizer free from overshoot, steady-state error and non-robustness.
