An optimizing design method for NCSs is presented to solve this kind of problems in the design of common NCSs controller with clock-driven sensors,event-driven controllers and actuators. In the design of networked control systems( NCSs) based on Lyapunov stability theory and linear matrix inequality( LMI),the number of variables in LMI often exceeds the number of LMI constraints,which may present the difficulty in solving the parameters of controller. The optimal controller parameters can be found on the basis of the gradient optimization. The simulation results show the effectiveness of the present method for UUV heading control system.
