Based upon the parameters modulation and the adaptive control techniques, we control the response system to be the drive system even though their orders are different and parameters are unknown. The techniques are successfully applied to three examples: Rössler hyperchaotic system (fourth order) and Rössler system (third order); Tamaševičius system (fourth order)and Rössler systems (third order); generalized Lorenz system (fourth order) and Lü system (third order). Furthermore, the effects of control modulator k and external noise are under our discussion.
