Abstract

In industrial processes, the most important loop is the liquid-level control loop. The coupled tank system CT-100 becomes an essential apparatus for process control researchers. This paper introduces two controller techniques to control the water level in the second tank as a single input single output system. The PID controller is designed to control the linearized model, where the controller parameters are tuned using the Ziegler- Nichols tuning method. In addition, Fuzzy PID is designed based on adequate knowledge and experience. The proposed control approaches are simulated using MATLAB Simulink. Then, the obtained results using these controllers are compared in terms of time response specifications and the ITAE criterion. It is also, tested for step-change tracking signal and disturbance rejection. Finally, the simulation results showed that the Fuzzy PID controller has a robust performance.

耦合储罐液位控制系统的模糊 PID 控制器设计

在工业过程中，最重要的回路是液位控制回路。耦合水箱系统 CT-100 成为过程控制研究人员必不可少的设备。本文介绍了两种控制器技术，以控制作为单输入单输出系统的第二个水箱中的水位。设计了 PID 控制器来控制线性化模型，控制器参数采用 Ziegler- Nichols 调节方法进行调节。此外，还根据充足的知识和经验设计了模糊 PID。使用 MATLAB Simulink 对所提出的控制方法进行了模拟。然后，从时间响应规格和 ITAE 标准的角度对使用这些控制器获得的结果进行比较。此外，还对阶跃变化跟踪信号和干扰抑制进行了测试。最后，仿真结果表明，模糊 PID 控制器具有稳健的性能。

期刊介绍： WSEAS Transactions on Systems and Control publishes original research papers relating to systems theory and automatic control. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with systems theory, dynamical systems, linear and non-linear control, intelligent control, robotics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
