【摘要】 先根据实际的测量数据对三阶液位系统进行建模研究,得到了它的过程模型;然后使用内模预测控制方法,讨论了系统的设计方法与步骤.在仿真试验中,研究了各参数不匹配时系统的动态特性,并通过合理的调节可实现因子,得到几组模型失配时的曲线.从仿真曲线中可以看出,内模控制在多阶液位控制中有应用价值.更多还原

【Abstract】 At first we established the model of the three order water reservoir according to the measure date in practice and got its process model.Then based on internal model predictive control method,we discussed the designing method and step of the system.In simulation experiment we researched the character of dynamic state for models with mismatched parameters.Through regulating a and b several charts for models with mi- smatched parameters are obtained finally.Simulation results show that internal model predictive control method has certain application value in the three order water reservoir.更多还原
