This paper demonstrates the closed-loop control of frequency and phase a fluidic oscillator using acoustic excitation. It is shown experimentally that use excitation modifies passive feedback mechanism slows down jet switching process. Closed-loop employed to vary oscillation at fixed flow rate track sinusoidal reference target without error, measurements from pitot probe in device. The control...

A dual-loop current control is discussed for LCL -type shunt active power filters (APFs), where inverter-side feedback and point of common coupling (PCC) voltage feedforward both provide damping (AD) effects resonance. However, two ADs are equivalently applied to different elements filter with ...
