Abstract :
A real-time active flow control methodology for complete elimination of objectionable fluid transients is introduced. It was found that the fluid transients can be completely suppressed by optimally operating a device which closely resembles an air chamber except that its air pressure can be actively controlled. Properly operated, this transients suppressor acts as a temporary storage and supplier of fluid to regulate the flow conditions. To control the device a nonlinear partitioned optimal control system is developed. Based upon that, an optimal problem is formulated and solved to determine the control gains for control implementation. Control system modeling and computer simulation are presented to highlight the capacity of this methodology
