Aiming at the "open" character of MIS, a "feedback control model" is put forward to enhance the maintainability, expandability and flexibility of MIS.

In-depth analysis of the Automotive braking process, a current feedback control model is introduced based on the energy error redeem, in order to improve the braking system simulation effect.

The article is based on coherent structures of turbulent boundary layer theory, studies the feedback control model of turbulence, and inputs control system to get the enhancement of heat transfer.
