absolute term can substitute for square term for nonlinear action, when the square term in lorenz-like system proposed by liu is replaced by absolute term, a new hyperchaotic system containing absolute term can be constructed by using proper feedback control method.

绝对值项的非线性化作用往往可以代替平方项，liu等人提出的类lorenz系统中平方项用绝对值代替，并利用合适的反馈控制手段，可以构造一种新的含有绝对值项的超混沌系统。
