Feedback Control of Flow Separation Using Plasma Actuator and FBG Sensor

Figure 9

Time-series of Bragg wavelength fluctuations () for 20 seconds under PA-OFF and PA-ON conditions which are detected by FBG sensor attached to exterior surface of cantilever (Figure 8(b)). (a) Under PA-OFF, intermediate value was found to be constant, at roughly 1540.08 nm. (b) On the other hand, tended to gradually increase over time under PA-ON.
