This paper proposes a new method of controlling chaos, from which we f
ind that the condition of negative Lyapunov exponent in a controlled c
haotic system is not necessary. By using a piecewise linear controller
, we successfully design a chaotic attractor to keep the output of the
controlled chaotic system in a small neighborhood of the target. The
analyses and experiments show that it is a practicable method. (C) 199
