Observers of control state and uncertainty using Takagi-Sugeno fuzzy model
Hugang Han, Yuki Sueyama, Chunjun Chen · 2017
Adding a term called uncertainty in the Takagi-Sugeno (T-S) fuzzy model to cover the difference between a real system concerned and its T-S fuzzy model, this paper proposes novel observers of the control state and the uncertainty. Unlike state observer in the traditional sense that is usually designed as a whole, following dividing the state into two parts by performing a unique matrix transformation, two observers of the state are designed separately in order to eliminate the influence of the uncertainty. Finally, an observer of the uncertainty based on one of state observers is provided.
