Abstract :
The paper suggests a new class of fuzzy control systems consisting of Takagi-Sugeno Pi-fuzzy controllers (PI- FCs) with Iterative feedback tuning (IFT) controlling servo systems with controlled plants characterized by second-order integral type models. An attractive stability analysis method dedicated to this class of fuzzy control systems is proposed making use of the specific matrix approach in terms of the nonlinearity vectors in the matrix space. One case study focused on the stable design of an IFT-based PI-FC implemented in controlling a servo system complements the theoretical results.
