In this paper, the problem of forcing the Chen’s chaotic attractor to track a sinusoidal and a chaotic reference signals in the presence of uncertainties in the system’s parameter values is addressed by combining the theory of robust regulation and the exact Takagi-Sugeno fuzzy model for the Chen’s chaotic attractor. On the basis of designing a robust controller for each linear subsystem, it is shown that the aggregated controller assures robust tracking in the presence of variations on the parameters of each linear subsystems and in the membership functions as well.
