基于PID控制的含能材料高精度压装技术是针对起爆器含能材料压装过程中,由于应力弛豫现象引起的伺服压机压力超差问题,分析其控制原理,根据PID控制的相关理论,研究引入积分控制和微分控制,提升压装过程中压机控制系统的动态性能和稳态性能,消除稳态误差并降低超调量,达到解决压力超差的效果。经试验验证,该方法能够有效提升伺服压机在含能材料压装过程中的控制精度,在火工品自动化装配领域具有显著的实际应用价值。
Based on PID control can contain material of high precision technology for installation of detonator can contain material in the process of being connected, caused by the stress relaxation phenomenon servo press pressure out-of-tolerance problem, analyzes its control principle, based on the related theory of PID control, the research into the integral control and differential control, improve process installation medium pressure machine control system dynamic performance and steady-state performance. The steady-state error is eliminated and the overshoot is reduced to solve the pressure overshoot. The experimental results show that this method can effectively improve the control accuracy of the servo press in the process of energetic material pressing, and has significant practical application value in the field of explosive automatic assembly.
