    Abstract: This study investigates the adaptive controller design for the Generalized Projective Synchronization
(GPS) of identical Liu-Chen 4-scroll chaotic systems, identical Lu-Chen-Cheng 4-scroll chaotic systems
and non-identical Liu-Chen and Lu-Chen-Cheng 4-scroll chaotic systems. Lyapunov Stability Theory is the
methodology used for establishing the adaptive GPS synchronization results derived in this study. Since, the
Lyapunov exponents are not required for these calculations, the proposed Adaptive Control Method is very
effective and convenient for achieving the Generalized Projective Synchronization (GPS) of the 4-scroll chaotic
systems. Numerical simulations are shown to demonstrate the effectiveness of the adaptive GPS
synchronization results derived in this study for the 4-scroll chaotic systems.
