Synchronization characteristics of an array of coupled MEMS limit cycle oscillators

The dynamics of a proposed microelectromechanical system (MEMS) consisting an array limit cycle oscillators (LCOs) are analyzed. LCOs have dissimilar frequencies and coupled in nearest-neighbor configuration via electrostatic fringing fields. emergence synchrony the is outlined for two cases: self-synchronization to single frequency, entrainment external inertial drive. Numerical analysis used study dependence on parameters such as coupling strength, detuning array, drive frequency It shown that route complex due formation clusters. equivalent oscillator, with averaged over estimate locking array. This oscillator approximate entire perturbation methods applied it. method qualitatively captures characteristics externally-driven also track sequence bifurcations occur strength changes, threshold entrainment.
