摘要
采用PLC作为现场液位控制器,在工业和日常生活中被广泛运用在液位控制系统中。提出了模糊PID算法对液位进行调节的控制策略,实现了液位控制响应速度快、稳定度好和准确度高的效果。测试表明,建立在模糊算法基础上的液位PID控制比常规PID控制具有更好的动态性能。此外,还采用CC-Link总线技术建立主从通信的工业网络系统,实现设备间的数据传送,并通过人机界面对现场液位进行实时远程监控。
In industry and daily life, PLC is widely used in liquid level control system. The control strategy with fuzzy PID algorithm is proposed, by which the liquid level control is faster, more stable and more precise. Re- suits show that the fuzzy PID has better dynamic performance than conventional PID algorithm. Furthermore, the industrial network of master-slave communication based on CC-Link can realize the data communication be- tween devices on the network, and the real-time remote monitoring to the liquid level on site with human-ma- chine interface.
