In this paper intelligent control and realization of the stable M large system for wind tunnel are introduced. This system is a complex and time-varying parameter nonlinear computer control system with three interrelated subsystems. It includes the optimal control subsystem of FL-7 wind tunnel engines with predicting function, ann-based adaptive control subsytem of bypass valve and flexible wall control subsystem. By means of optimal control principle and intelligent control technique, many-goal optimal control design objective is implemented. Test in tunnel operation proves that this control system is precise for stable M , robust, fast and less consumption of oil.
