摘　　要：本文针对存在大滞后、时变、非线性特点的液位控制,基于模糊规则参数自整定PID方法,设计了一种基于模糊规则参数自整定PID控制器。该控制方法可以在线实现PID参数的调整,并运用MATLAB进行了仿真研究,与传统控制方法如PID控制相比,使控制系统的响应速度快,超调量减少,过渡过程时间大大缩短,振荡次数少,具有较强的鲁棒性和稳定性。文中利用数据采集卡PCI-9118DG进行数据的采集和输出控制,保证了数据传输可靠和速度。This article for the existence of large time delay, time-varying, non-linear characteristics of liquid level control, fuzzy rule-based self-tuning PID parameters, the design parameters of a fuzzy rule-based self-tuning PID controller. This control method can achieve the PID parameters online adjustments, and conducted a simulation using Matlab, with the traditional control methods such as PID control, compared to control system response speed, overshoot decreased, the transition process takes much less time, oscillation frequency less, with robustness and stability. Paper using data acquisition card PCI-9118DG for data acquisition and output control, ensuring data reliability and speed.
