Along with calculator technique with high and new technical and fast development in etc. in technique in information, imitate the true technique too push getting quickly, its in control system develop of the function also shows the importance more .This text introduces to imitate the true technical concept, characteristics, development circumstance primarily and its at application that control the system; Analyzed the MATLAB/ SIMULINK function and how to provide in the language of MATLAB of imitate the true environment SIMULINK descend to practice to control the system really imitate, and with a design for permitting water tank liquid controlling system for example in detail proceeding system with really imitate; In addition, still introduced a configuration software to imitate the true application in the system in the process. Pass from the treatise of the above aspect, get a conclusion: Make use of the calculator to the control system proceed imitate true with analyze, is the important means of the system of control of research; The software of MATLAB, MCGS a configuration software can used for successfully the control system realizes imitate and analyze and supervise and control, Study, produce in science to have the extensive and applied foreground with teaching etc. realm with expand the value.
