This paper investigates the problem of generalized functional projective synchronization of Chen-Lee systems. Based on Lyapunov stability theory, an effective control law is designed for asymptotic stability of the null solution of an error dynamics between master and slave chaotic systems. In order to verify the effectiveness of proposed control scheme, computer simulation via Matlab software is applied to a numerical example and then its circuit implementation is included as real applications.
