Based on the theory of impulsive differential equations, this paper studied the asymptotic stability of hyperchaotic complex Lü system under the stochastic impulsive signal. Some criteria were derived for the stabilization of the complex system via an impulsive method. And we also presented the estimate of the stable regions for the equal impulsive intervals. Numerical simulations demonstrated the effectiveness of the theoretical results and also showed that the method was robust against the noise.
