【Abstract】 A series of experiments are decentralized in the course of Process Control System,in accordance with the inherence relation and the sequence of the experiment content,which is integrated the organic synthesis,to apply the Matlab simulation in the experiment of process control system,which is set on the real experiment device.According to actual measurement it gains the model of the experiment target which serves as the prototype of the simulation,and in terms of the real situation of the experiment device establishing the Simulink model,using the Simulink model proceeds the Matlab simulation obtains parameters(PID controller) of the control system,then using these parameters guides the experiment to run the real device of the control system.Experiment contents are designed which comprise the model measurement of real target;and all experiments are from simple system to complex system.The tool of the comprehensive experiment adopts the combination which is the Matlab simulation with the experiment on real device.To apply this method can improve the efficiency of experiment and attain good results of teaching.The level cascade control system is served as an example which emphasizes to illustrate the method of experiment teaching and it represents to obtain good teaching results,it can also apply the simulation method on other experiment teaching of control engineering course.更多还原
