In this paper, the concept of robust filter is established and the filter design for a class of uncertain chaotic systems is investigated. Based on differential and integral inequalities, a linear filter is proposed to realize the global exponential stabilization of uncertain chaotic systems. The guaranteed exponential convergence rate can also be correctly estimated. Besides, some numerical simulations with circuit realization are provided to show the capability and feasibility of the obtained result.
