H∞ fuzzy predictive control of non-linear NCS with packet loss

This paper studies the problem of H_∞ fuzzy predictive control of non-linear systems under networked environment where packet loss may occur. The non-linear controlled plant in the networked control systems (NCSs) is represented by a Tagaki-Sugeno (T-S) fuzzy model. Packet loss is assumed to happen intermittently in the sensor to controller link and controller to actuator link, and stochastic variables satisfying the Bernoulli random binary distribution are utilized to describe the unreliable communication phenomenon. H_∞ fuzzy predictive controller is designed to guarantee that the closed-loop system is stochastically stable and preserves a guaranteed H_∞ performance. A set of linear matrix inequalities is given to solve the corresponding controller optimization problem. A numerical example is given to illustrate the effectiveness of the proposed method.
