Abstract:

The NCS adopting industrial communication networks has many advantages, such as openness, high-speed, powerful hardware and software technical support and so on. But uncertain time-delay in networks has a great influence on the stability and control performance of systems. For an actual NCS, it should not only run steadily, but also satisfy a certain function index. At the same time, the applied statefeedback is the most effective control mode that takes account of both system function and sensibility. A class of state-feedback NCSs with uncertain time-delay are converted to the uncertain linear time-delay systems. Then by using the Lyapunov theory and LMI,the problems about guaranteed cost control are researched. The condition of existence of the guaranteed cost control law and the design method for the NCS are derived, and the design of an optimal guaranteed cost control law is given.
