Discussion on: 'Exponential Stability Based Design of Constrained Fuzzy Predictive Control'

摘要

The paper by Khairy, Elshafei and Emara introduces the so-called "First Point Constrained Method" to design a stabilizing MBPC. In this method, a discrete Takagi Sugeno (TS) fuzzy model of the constrained nonlinear process is used both as a model of the process for the receding-horizon optimization of the MBPC, as well as to compute a stabilizing fuzzy state feedback controller based on a quadratic Lyapunov function V(k) = x_e~T(k)Px_e(k). Moreover, a constraint on the applied control action is used to ensure the decrease of the quadratic Lyapunov function.
