| 摘 要： | 三容系统是一种典型的非线性、时变、强耦合系统，它能较好地模拟非线性多容器流程系统，对其液位控制算法进行研究很有实际意义。该文以三容系统的液位为被控对象，把模糊控制技术应用于控制系统的设计中。利用Matlab软件中Simulink工具箱搭建系统，通过确定模糊规则和隶属度函数，来调节模糊控制器，使之有效地控制系统的液位。仿真结果表明：与传统PID控制算法相比，模糊控制算法是实现多容器流程系统控制的一种有效算法。

| Abstract: | Three -tank system is a typical non -linear, time -varying, strong -coupling system. It can simulate nonlinear multi -tank system better, which has a very practical significance to the study of liquid level control algorithm. In this paper, liquid level of three - tank system is choosen as the object, and the fuzzy control technology is used in control system design. The system is built by Simulink toolbox in Matlab software, the fuzzy controller is adjust through the fix of fuzzy rules and membership functions so that it can control system level effectively. The simulation results show that compare with the traditional PID control algorithm, fuzzy control algorithm is an effectively control algorithm which implements multi - tank system. |
