| Abstract: | In this paper, we study the hybrid-triggered dynamic output feedback-based guaranteed cost control issue for uncertain Takagi-Sugeno (T-S) fuzzy networked control systems (NCSs) with cyber attack and actuator saturation. The hybrid-triggered mechanism comprising of time-triggered mechanism (TTM) and event-triggered mechanism (ETM) is provided to adjust the trigger strategy due to the variety in network resource utilization. Both the switching between two trigger mechanisms and the cyber attack phenomenon in communication network are respectively represented by two Bernoulli distributions. The data quantization is characterized by the sector bound technique and actuator saturation is addressed by invoking an auxiliary matrix. The stability of closed-loop NCSs with bounded disturbance and cyber attack is expressed by the methodology of quadratic boundedness (QB). The existence criteria and design strategies for minimizing the upper bound of performance in view of dynamic output feedback controller are constructed for any admissible uncertainties. Subsequently, in the light of the cone complementarity linearization (CCL) algorithm, the controller design issue is cast into the convex optimization issue which is capable of solving by the technique about linear matrix inequalities (LMIs). Finally, simulation example is employed to demonstrate the validity of designed controller. |
