Multiple Models Approach in Automation - Takagi-sugeno Fuzzy Systems

Klappentext Much of the work on analysis and synthesis problems relating to the multiple model approach has been motivated by the desire to establish the problems of control law synthesis and full state estimation in numerical terms. This book concentrates on the analysis of the stability and synthesis of control laws and observations for multiple models.
