Controller Design for Discrete-Time Affine T-S Fuzzy System with Parametric Uncertainties

파라미터 불확실성을 갖는 이산시간 어핀 T-S 퍼지 시스템의 제어기 설계

This paper proposes a stability condition in discrete-time affine Takagi-Sugeno (T-S) fuzzy systems with parametric uncertainties and then, introduces the design method of a fuzzy-model-based controller which guarantees the stability. The analysis is based on Lyapunov functions that are continuous and piecewise quadratic. The search for a piecewise quadratic Lyapunov function can be represented in terms of linear matrix inequalities (LMIs).
