Consequently, for the common reticulated domes, two instability patterns were identified, i.e. progressive instability and synchronous instability.
Here we present two instability mechanisms that can arise in filtered-E control that violate the 90° error assumption: feedback loop instabilities and LMS algorithm divergence.
By comparing the two instability potentials for the real and virtual rigid displacements, the total instability potential was recovered, which differs from the existing ones in the inclusion of the torsional terms.
Two instability events had been identified in the greater Sydney area, but both were considered minor by the meteorological agencies.
The three instabilities are saddle-node bifurcation (coexistence of multiple solutions), period-doubling bifurcation (subharmonic oscillation), and Neimark bifurcation (quasi-periodic oscillation).
Similarities and differences in various kind of plasma processes like gradient drift instability, two stream instability and wind induced effects at both the locations are discussed.
