摘　　要：首先,依据实际背景,利用单水箱实验系统设计了几种典型的液位控制实验;然后,将模糊推理建模法应用于实际的单水箱液位控制系统中,推导得到其数学模型,即变系数线性微分方程组;最后,利用仿真实验检验了这些数学模型的准确性。结果表明这种建模方法比较精确,充分考虑了实际系统的非线性特性。First, several level control experiments based on single tank system were designed in view of different applications. Afterwards, the mathematical models of these systems deduced with fuzzy inference method were given. At last, these models were testified by simulation. The result shows that the fuzzy inference method has high precision and can be used in non-linear systems in practice.
