文摘

A robust stagnation pressure controller for a supersonic wind tunnel is designed. The models of the facility and the controller are developed and used in simulations. An embedded distributed control system is developed on a FPGA-based platform. The control system is verified in the wind tunnel experiments at Mach 1 to Mach 4. The method is applicable to any blowdown facility requiring supersonic flow control.
