根据传统手工浇注的工艺特点,建立浇口液位的控制模型,提出以工业摄像法检测浇口液位、模糊PID控制算法设计浇口液位控制器的自动浇注系统。根据浇注工艺要求,采用MCGS组态软件、智能仪表AI808设计了自动浇注液位控制系统。结果表明,模糊PID技术能有效地抑制系统中存在的扰动,通过提高控制器的增益,可以提高系统工作频率和液位控制精度,改善浇注品质。 According to the characteristics of the traditional hand-casting technology, the control model of the gate level was established. The automatic pouring system was designed by using the industrial camera to detect the gate level and the fuzzy PID control algorithm to design the gate level controller. According to casting process requirements, the use of MCGS configuration software, intelligent instrumentation AI808 designed automatic pouring level control system. The results show that the fuzzy PID technology can effectively restrain the disturbance existing in the system. By increasing the gain of the controller, the system working frequency and liquid level control accuracy can be improved and the pouring quality can be improved.
