研究了放电等离子烧结（SPS）过程中温度的比例积分微分（PID）控制的稳定性。针对不同的SPS模具尺寸、物理参数条件和温度控制区域，测试了该过程的PID调节。结果表明，PID调节质量很大程度上取决于发热区域与温度控制区域之间的加热时间滞后。模具温度速率图进行了研究，以揭示高效PID控制的潜在领域。该模型和实验的收敛表明，即使与非最佳的初始PID系数，它是可能的，以减少温度调节的不准确性小于4 K定位的温度控制位置在高响应区域揭示的温度空间分布的有限元计算。(C)2017作者由Elsevier B.V.出版。这是一篇开放获取的文章，在CC BY许可证下
The stability of the proportional-integral-derivative (PID) control of temperature in the spark plasma sintering (SPS) process is investigated. The PID regulations of this process are tested for different SPS tooling dimensions, physical parameters conditions, and areas of temperature control. It is shown that the PID regulation quality strongly depends on the heating time lag between the area of heat generation and the area of the temperature control. Tooling temperature rate maps are studied to reveal potential areas for highly efficient PID control. The convergence of the model and experiment indicates that even with non-optimal initial PID coefficients, it is possible to reduce the temperature regulation inaccuracy to less than 4 K by positioning the temperature control location in highly responsive areas revealed by the finite-element calculations of the temperature spatial distribution.
