In this paper, we consider the problem of complete switched adaptive modified function projective synchronization (CSAMFPS) of two-stage chaotic Colpitts oscillators with uncertain parameters and disturbance inputs. Based on Lyapunov stability theory, adaptive controllers and sufficient parameters updating laws are designed to achieve the complete switched modified function projective synchronization between two identical drive-response structures of two-stage chaotic Colpitts oscillators. The external disturbances are considered in the drive and response systems in order to verify the robustness of our strategy. Numerical simulations are performed to show the effectiveness and robustness of the proposed scheme.
