The robust integrity design of nonlinear control system under the network environment

For a class of nonlinear control system under the network environment, both delay and packed dropout in transmission are addressed. A T-S fuzzy model is employed to represent the nonlinear controlled plant. By using appreciate Lyapunov-Krasovskii function, the robust integrality sufficient conditions of systems with failures of actuator or sensor is analyzed based on delay-dependent approach, and the fault-tolerant control gain can be obtained. The lower bound of the time-delay is introduced in the function, and the free variables which integral inequalities bring are taken advantage of. It guaranteed that does not carry on magnifying or ignoring and the model transformation to integral inequalities, then a less conservative results is obtained. Finally, an example is used to illustrate the effectiveness and feasibility of proposed approach based on OPC technology.
