This book focuses on a particular domain of Type-2 Fuzzy Logic, related to process modelingand control applications. It deepens readers’understanding of Type-2 Fuzzy Logic with regard to the following three topics: using simplermethods to train a Type-2 Takagi-Sugeno FuzzyModel; using the principles of Type-2 Fuzzy Logic to reduce the influence of modeling uncertainties on a locally linear n-step ahead predictor; and developing model-based control algorithms according to the Generalized PredictiveControl principles using Type-2 Fuzzy Sets.
