摘　　要：对水箱系统设计一个两维模糊控制器,模糊控制器设计为两个输入一个输出,模糊控制器的输出用来控制阀门的开度,调节水箱的液位。运用MATLAB模糊工具箱实现双输入单输出的模糊控制器,并结合Simulink仿真得到实际液位跟踪给定液位的曲线,仿真结果证实该模糊控制器优越于常规的PID控制器,水箱模糊控制系统获得良好的控制性能指标。A two-dimensional fuzzy controller for water-tank system is designed with dual input and single output.The fuzzy controller output regulates valve and makes the water-tank level up to the set point.The fuzzy controller with dual-input and single-output is made by using MATLAB fuzzy toolbox.The curve of the actual level tracking the desired level is gained through simulink simulation.Simulation results show that this fuzzy controller is superior to the traditional PID controller.The water-tank fuzzy control system possesses good control performance.
