摘要
液位是工业生产中的重要参数之一,对液位的测量和控制效果直接影响到产品的质量。着重介绍一种基于VB语言的复合液位控制实验系统,本系统采用PID控制、模糊控制和前馈控制来解决液位控制中存在的非线性、时变、大滞后的缺点,使系统达到稳定、鲁棒性强、超调小、抗干扰、快速响应、精确、运行可靠、节能的理想控制效果。
Liquid level is one of the important parameters in industrial production. For the liquid level measurement and control,the quality of the products is directly affected. This paper introduces a compound liquid level control experimental system based on the VB language. The system uses PID control, fuzzy control and feed forward control to solve the shortcomings of the nonlinear, time - varying and large delay in the liquid level control to achieve stable, robust, small overshoot, anti -jam- ming, rapid response, accurate, reliable operation, energy - saving ideal control.
