| This thesis is concerned about the research of Networked Control Systems(NCS), I primarily pay attention to the Guaranteed Cost Controller(GCC) and H_∞ controller's design. At the same time the time-delay and data dropout induced by the network are included as well as the uncertainties of the linear system and the external disturbance on the system are contained. Firstly, the definitions on the GCC and H_∞ control and the exponential stability are given. Secondly, based on the Lyapunov function, Linear Matrix Inequality and adding zeroes method, the sufficient conditions of asymptotical stability and exponential stability are obtained, meanwhile the design methods of GCC and H_∞ are proposed, and a new optimal algorithm is designed to solve the GCC'bound which is not a convex problem. Finally some simulate examples are given to show the effectiveness of the algorithm. |
