摘　　要： 针对PID对大滞后大惯性系统的控制效果不佳、参数整定复杂等方面的不足,将内模控制与PID控制相结合,并在MATLAB环境下进行仿真.以算例证明内模控制与PID控制串级结合,比单纯的PID控制具有更良好的鲁棒性和抗干扰性,不但调节速度更快,参数整定方法更简单,而且还不依赖于对象模型的参数,非常适用于工业过程控制. PID parameter-control has achieved in lots of fields in the industrial proceeding control, however, as the request of the control system improve, and the control object changed, PID could not present as satisfy as demand. In view of insufficient intensity control over the PID in the time delay inertial system, we compare the combination of IMC and PID cascade control with it in this article and simulation in the MATLAB. Along with robust and anti-interference, IMC-PID is not only easier adjusted in speed and tuned in parameter, but also it rarely relies on the parameter of the model. So it can be applied to many projects.
