Abstract

This paper introduces a novel concept termed Smart Mesoflaps for Aeroelastic Recirculation Transpiration (SMART) for controlling shock/boundary-layer interactions (SBLI) in supersonic jet inlets. The control strategy for a subsystem of the SMART project, subject to hysteresis and actuator saturation, is presented. A Hysteresis Compensation scheme, as well as results from experimental application of HC to the SMART system are presented next. A generalized error governing scheme for PID controllers to compensate for actuator saturations is also developed. Finally, the PID with HC and the error governing method is experimentally applied to a benchtop SMART subsystem and is shown to be successful at preventing excessive control efforts.
