Continuous time-invariant optimal fuzzy tracker design based on local concept approach

We propose a global optimal fuzzy tracking controller for continuous time-invariant fuzzy tracking system to trace moving or model-following targets under an infinite-horizon (time) quadratic performance index. We also demonstrate that the stability of the closed-loop fuzzy tracking systems can be ensured by the designed optimal fuzzy tracking controllers. One example is given to illustrate the proposed optimal fuzzy tracker design scheme and to show the proved stability property
