From an engineering perspective, it is well known that there are numerous problems to
predict and control complex systems. In addition, there are also problems to understand the …

In this paper, the problem of the control for an uncertain nonlinear chaotic system has been
studied; based on fuzzy logic, a kind of single‐dimensional controller is constructed for the …
