Electron Beam 3D Printing Fuzzy-PID Temperature Control System

针对电子束3D打印温度控制系统,采用自整定模糊PID控制,使用MATLAB模糊逻辑模块及仿真模块建立系统仿真图,通过仿真曲线获得优化参数。结果表明,与模糊控制系统及PID控制系统相比较,自整定模糊PID控制系统在电子束3D打印温度控制系统中具有动态响应快、调整速度快、稳态性能高、超调量小等优点。

In the electron beam rapid forming temperature control system,the adaptive fuzzy-PID control method is adopted.The MATLAB fuzzy logic module and simulation module are used to establish the simulation system.The results show that compared with traditional fuzzy control system and PID control system,the adaptive fuzzy-PID control system has some advantages,such as fast dynamic response,short adjustment time,minimal stable error and low overshoot.
