  A method of targeting engineering synchronization states in two identical and
mismatch chaotic systems is explained in details. The method is proposed using
linear feedback controller coupling for engineering synchronization such as
mixed synchronization, linear and nonlinear generalized synchronization and
targeting fixed point. The general form of coupling design to target any desire
synchronization state under unidirectional coupling with the help of Lyapunov
function stability theory is derived analytically. A scaling factor is
introduced in the coupling definition to smooth control without any loss of
synchrony. Numerical results are done on two mismatch Lorenz systems and two
identical Sprott oscillators.
