In each synchronization scheme, a single control function is designed to achieve projective synchronization between two Bonhöffer-van der Pol oscillator evolving from different initial conditions. To obtain a single control function via the active control, the coefficient of the error dynamics is chosen such that the number of control functions is reduced from three to one, thereby, reducing control function complexity in design. The results show that the transient error dynamics convergence and synchronization time are achieved faster via the backstepping than that of the active control technique. However, the control function obtained via the active control is simpler with a more stable synchronization time and hence, it is more suitable for practical implementation. Numerical simulations are presented to confirm the effectiveness of the analytical results.
