Robust control for fuzzy singular perturbed unified model

In this paper, we propose a fuzzy singular perturbed unified model which can be used in both continues-time domain and discrete-time domain. The sampling period should be the same order small amount of the singular perturbation parameter ε and ε ≪ 1 in fuzzy singular perturbed systems. Hence, the unified model makes use of delta operator which takes numerical advantages in high speed sampling system. In the proposed model framework, the problem of robust control is addressed. Furthermore, the singular perturbation parameter independent solution is also obtained. Some simulation results are given to show the effectiveness of the proposed approach.
