Astrocyte-inspired controller design for desynchronization of two coupled limit-cycle oscillators

In this paper, a biologically inspired controller is proposed for desynchronization of two coupled limit-cycle oscillators. Recently, researchers have shown that “astrocyte” has the potential to desynchronize the synchrony between two coupled neurons. So, first, based on the astrocyte model, the structure of the dynamic controller is suggested. Then, controller parameters are tuned through an optimization algorithm. The suggested controller has 3 important properties: 1) the controller desynchronizes the oscillators without any undesirable effects on the inherent behavior of oscillators (e.g. stopping, annihilating or starting divergent oscillations); 2) it requires little effort to maintain the desirable desynchronized state; and 3) the controller is robust with respect to parameters variations. Simulation results reveal the efficiency of the proposed controller.
