Description: PID 控制在过程工业控制中应用广泛, 但在实际工业现场运行的PID 回路的控制
性能差异较大, 有许多系统长期置于手动控制。一部分由于系统过程特性使PID 调节不能满足
控制要求, 还有一部分却是由于PID 回路参数整定的不合理。针对控制系统现场实施中PID 参
数整定繁琐、整定质量差异大、经验不易移植的问题, 采用了基于PLC 的PID 参数自整定方
法。该方法概念清晰, 实施方便, 在某锅炉的恒压供水控制中应用效果良好。该方法基于继
电器反馈自整定, 具有一定的普适性, 对工程实施人员要求低, 易于推广。-PID controllers are widely used in process industry. But the control quality of PID loops operating is different in industrial fields and
many of them have to be switched to manual mode. Some of them are attributed to process dynamics characteristics which make PID tuning be
unsatisfied to control requirements, but some are due to poor turing of PID parameters. In light of the tediousness and difficulty of PID tuning ,
an auto tuning method based on PLC is adopted to ease the procedure. The adopted PID auto tuning is simple in theory, easy to conduct and
it is satisfied in a constant pressure water supply system. Based on relay feeedback auto tuning, this method can be easily applied to other pro
cesses. Platform: |
