3D打印机的定位模糊控制

Research on Positioning Fuzzy Control of 3D Printer

为了应对3D打印机定位控制中步进电机所表现出的高度非线性特性,首先设计了步进电机的仿真模型,在传统PID控制的基础上设计了参数模糊自整定PID控制。最后通过Simulink分析了所设计的控制方案。结果表明,该方法反应更迅捷,超调量更小,较好地提高了系统稳定性,更加满足了机器对定位精度的要求。

For the non-linear characteristics of stepper motor positions control of 3 D printer, we estab- lished a mathematical model of the stepper motor. We designed fuzzy parameter self- modulated PID controller based on the traditional PID control method, and control method through Simulink platform. By comparing the experimental results, the control method was short response, less overshoot, good positioning effect, which can better meet the requirements of positioning precision.
