| 摘 要： | 针对三容水箱是较为典型的非线性、时延时象，具有很强的代表性这一特点，通过机理建模方法建立了三容水箱的一般数学模型。分析了线性和非线性阻力板的流量特性，并通过实验测定了阻力板流量系数。最后给出了三容水箱的线性化模型。由仿真实验可知，非线性模型的阶跃响应和实验测得的响应曲线相吻合，说明用该方法建立的数学模型是正确的和可行的。

| Abstract: | To the three-tank water,a typically non-linear and delayed plant,the general mathematic model of three-tank water is established by means of mechanism modeling method,and the characteristics of both linear and non-linear weir flow meters are analyzed.The flow coefficients of weir flow meters are determined by experiment,and the linearization model of three-tank water is obtained.Step response of the model complies with experimental result so that the proposed model is correct and practical,and lays the foundation for the research on the advanced control strategy of three-tank water. |
