Fuzzy H∞ tracking control for a class of nonlinear networked control systems with a discrete event-triggered communication scheme

This paper investigates the fuzzy H_∞ tracking control problem for a class of nonlinear networked control systems (nonlinear NCSs) via the Takagi-Sugeno (T-S) fuzzy model. Introducing a novel discrete event-triggered communication scheme and considering the effect of transmission delay, a new fuzzy H_∞ tracking model of nonlinear NCSs is established with a delay system approach. Based on a fuzzy Lyapunov function approach, a co-design method for tracking feedback control gain and trigger parameters that guarantee the prescribed H_∞ tracking performance of nonlinear NCSs is derived in terms of linear matrix inequalities. Finally, a numerical example is given to show the effectiveness of the proposed method.
