摘要
针对温度控制中PID算法系数较难整定的问题,将单片机采样结果通过串行通讯传送到PC机并用LabVIEW实时监测,在此基础上采用积分分离、微分滞后的PID算法,以实现对温度的高精度控制。实验结果表明它可以快速,准确地实现对温度的高精度控制,效果明显优于传统PID算法,且系数整定简单方便,可以使调试周期明显缩短。
To aim at the coefficients adjust in PID algorithm of temperature control, send Single Chip Micyoco sampling results through serial communication to a PC and used Labview real-time monitoring. On this basis, we use the integral separation and the differential delay PID algorithm to achieve the high-precision temperature control. The results show that it can achieve the high-precision temperature control fast and accurately. The effect is superior to conventional PID algorithm, while the set of coefficient is simple and convenient, and it can significantly shorten the debugging cycle.
