Abstract：The three-tank water system which is multivariable,nonlinear and coupled with each other makes it difficult to es?tablish accurate mathematical model,for the problem,the design of predictive control algorithm based on RBF-ARX model are dis?cussed. This modeling method is a combination model based on the theory of neural network RBF(Radial Basis Function)and lin?ear autoregressive ARX(Auto-Regressive eXogenous)model,it is used to construct the model of nonlinear system. Predictive con?trol algorithm predicts system 's output,and makes the error minimum through closed-loop control. The structure of the three-tank water system 's RBF-ARX model is built firstly,then the model 's parameters are identified and optimized. Predictive control algo?rithm is taken to control the three-tank water system based on this model,the real-time control verify the feasibility and validity of the method.
