Observer-based control for a class of nonlinear networked control systems

  • Considering the data packet dropout between sensor and controller, when some states of the object cannot be measured directly, a class of networked control systems (NCSs) with nonlinear perturbing terms in the plant was investigated. There is a network between the sensor and controller. The network was considered as a switch, which happened between sub-system when network communication was connected and sub-system when network communication was interrupted. So the NCS could be modeled as a switched system. Motivated by dwell-time idea, some sufficient conditions of exponential stability of NCS were established by Lyapunov stability theory. Utilizing the solutions of linear matrix inequalities (LMIs), the parameterized expression method of the state observer and controller was given which could ensure the NCS exponential stability. A numerical example was shown to demonstrate the efficiency of the obtained result.
