针对恒压供水控制系统，运用模型预测控制方法进行了建模和仿真。该方法利用带遗忘因子的加权递推最小二乘法对模型后件参数进行在线辨识，减小模型失配造成的对控制性能的影响；将非线性供水系统模型转化成线性时变状态空间模型，并由此实现对模型输出的预测，并通过滚动优化不断得到最优的预测控制输入，反馈校正过程提高了控制输出精度。仿真分析验证了该方法在供水过程中的灵敏性和准确性。

In view of the constant pressure water supply control system, applied the model predictive control method to modeling and simulation. The method used weighted recursive least squares method with forgetting factor to identify the consequent parameters of model online and to overcome the influence of model mismatch on the control performance; The nonlinear model of water supply system was converted into linear time-varying state space model, and on the basis of the model, achieved the prediction of model output. Through the rolling optimization obtained the optimal predictive control input constantly, and the feedback correction process improved the output precision. The simulation analysis verified the sensitivity and accuracy of the method in water supply.
