Model-Based Design on the Application of Active Flow Control System

Abstract:

Active flow control has produced a great many values in the S-shaped inlets. In this study, the pressure gradient is used to characterize the degree of flow reattachment on the S-shaped inlet and be referred as the pressure recovery parameter^[1]. A transfer function is established between an input of frequency of the solenoid valve and an output of the pressure gradient. According to the process of model-based design, one of Simulink model created by Different Control Algorithms which are applied to the established system in the simulation is selected to generate C codes automatically. The generated codes are embedded in the ARM7 processor and the test result of the processor is consistent with simulation.
