Concept of a Positive Velocity and Position Feedback (PVPF) controller is introduced and a controller is designed to damp this undesired resonance mode.
For verifying the proposed PAVPF-based control approach, comparative experiments with positive velocity and position feedback controller and with PI controller are conducted on a piezo-actuated nanopositioning stage.
The largest negative velocity is 411 km/sec (kilometres per second) for NGC 6934, while the largest positive velocity is 494 km/sec for NGC 3201.
The positive velocity reflects the flood dominance, while the negative velocity reflects the ebb dominance.
Similarly, the spacecraft motion, which has positive velocity away from the Earth, causes a positive shift in the counter.
We investigated two control methodologies (positive velocity feedback and H∞ control) and two types of actuators (an inertial actuator and a distributed strain actuator).

Similarly, the point movement in the outer direction is related to positive velocities.
As can be observed, the strong echoes have high positive velocities with a maximum of 60 m/s, indicating a southward (equatorward) motion of the echo targets.
In this figure we can identify five oblique striations with negative Doppler velocities between 1500 12 (start time of the themisscan) and 1510 JST, and one oblique striation with positive velocities during 1500 12 1501 30 JST.
From an initial analysis, Nishitani et al. (2011) identified the 6.2 km/s disturbance with positive velocities between 1500 12 and 1501 30 JST and other disturbances of 3.5, 3.9 and 4.5 km/s, in line with the current analysis.
