摘　　要：为提高熔融沉积型3D打印机过程控制系统的可靠性,基于自动控制理论将Fuzzy-PID控制方法应用于3D打印机喷头温度控制系统。通过实验数据采集,在Matlab中建立以3D打印机喷头温度为被控对象的仿真模型,确定模糊规则表与模糊查询表,设计相应的Fuzzy-PID控制器,实现3D打印机喷头温度Fuzzy-PID控制,同时与采用PID控制、普通模糊控制两种方法对喷头温度的控制效果作比较。通过分析仿真结果,验证了采用自适应Fuzzy-PID控制方法的3D打印机喷头温度控制系统可缩短调节时间、降低超调量、减小稳态误差,还可以提高抗干扰能力,控制能力优于PID控制与普通模糊控制,具有较强的可靠性。In order to improve the reliability of the fused deposition process control system,the Fuzzy-PID control method is applied to the 3D printer nozzle temperature control system based on the automatic control theory.Through the experimental data acquisition,simulation model of the 3D printer nozzle temperature as the controlled object is established in Matlab,the fuzzy rule table and the fuzzy query table are determined,and the corresponding Fuzzy-PID controller is designed to realize the 3D printer nozzle temperature Fuzzy-PID control.At the same time,the control effects of the nozzle temperature are compared with the two methods of PID control and general fuzzy control.By analyzing the simulation results,it is verified that the3D printer nozzle temperature control system which adopts the adaptive Fuzzy-PID control method can shorten the adjustment time,reduce the overshoot and the steady-state error,and improve the anti-interference ability;its control ability is better than PID control and common fuzzy control,and it has strong reliability.
